Zac at ortholog.com writes about an experimental test of buying irrationality using Ebay. Quoting:

Test auctions on eBay showed that most people prefer to pay a low price for an item and also pay postage (American: "shipping") than pay a higher price and get free postage, even when the former added up to more than the latter. A CD for $5+$6 postage is preferred to a CD for $10+freepost. It wasn’t presented as that stark a choice: multiple auctions with different price-postage ratios revealed a net preference for low item price and a poor correlation between auction success and stated postage costs. Interesting but hardly surprising: the salience of the price is greater than the cost of shipping (the anchoring cognitive fallacy), and people in general are not as rational or systematic as they/we believe.

In Influence, Cialdini highlights scarcity as one of the six principle factors of persuasion. In an auction they combine particularly strongly: scarcity of time (the item is only on sale for a limited period), scarity of product (items are sold individually, not just as one-of-many ‘off the shelf’) and competition (from other buyers). Add to this heady mix the price/postage sleight of hand and it is no wonder you get choice irrationalities.

Influence by Robert Cialdini is an excellent, excellent, book. Not only does it present voluminous evidence on the social psychology of persuasion and compliance, but it does succinctly and engagingly, mixing academic references with historical vignettes and personal anecdotes. The book discuss how techniques of persuasion work, grouping them under six major headings, and for each heading the book provides a ‘defence against’ section detailing how to stop yourself being unduly influenced. The final, glorious, touch is that in order to write the book Cialdini – who is a professor of social psychology – engaged in a three-year project of going undercover to explore first-hand how techniques of persuasion are used in the real world: applying for a waiter’s job to study how to increase customers’ tipping, attending tupperware parties, going on training programmes with door-to-door salesmen…it makes the book a wonderful blend of thorough research and astutely observed practice.

The book has been extensively and excellently summarised here, at happening-here.blogspot.com, so I’m just going to pull out some particularly fun examples of persuasion techniques, particularly as the relate to advertising and marketing.

Notes on Cialdini, R.B. (2001). Influence: Science and Practice. Forth Edition. Allyn & Bacon

A key idea is that we all use various cognitive ‘shortcuts’ (heuristics) we use to decide on what to buy. Advertisers can take advantage of these short-cuts to skew our behaviour. For example, there is a price-as-an-indicator-of-quality heurstic which means, if we’re not thinking carefully about a purchase decision, we might just use the assumption that

The Implicit Association Test [1] is a sorting task which reveals something about our automatic, non-deliberate, associations [2].

The part of the test which betrays our automtic associations is a combination of two simpler sorting tasks. Both simple tasks involve sorting words and pictures into categories which are assigned to the left and right (by pressing the E and I keys, which are on the left and right of your keyboard). One task is to sort words (like ‘love’, or ‘failure’) into the categories ‘good’ and ‘bad’. The other task varies depending on what you want to detect automatic associations about. In the ‘race IAT’ the task is to sort pictures of the faces of white americans and the faces of black americans. The race IAT isn’t the only version, but it is the most (in)famous (you can also do the IAT on fat vs thin, arab-muslim vs non-arab-muslims, for different US presidents and in many other variations). The compound task involves sorting both words and pictures to the left and right where each side has two categories assigned to it – so ‘good’ and ‘black american’ on the left, and ‘bad’ and ‘white american’ on the right, for example.

What the IAT test does is compare your times for sorting good words when the ‘good’ side is also the ‘white’ side to when the ‘good’ side is also the ‘black’ side (and vice versa for sorting bad words, and for sorting white and black faces to the good and bad sides). By doing these comparisons the test can detect any evaluation of ‘white’ or ‘black’ as positive or negative that is affecting your time to classify the words or faces to the correct side. So, for example, if you take significantly longer to sort good words to the ‘black’ side than you do to the ‘white’ side then the result is an automatic preference for ‘white americans’ over ‘black americans’ [3]

What the Racial IAT indicates is that most Americans have an automatic preference for whites over blacks. Two things are important about this. First it isn’t really clear what mechanisms lie behind the effects found in the test (‘Voodoo’ is one suggestion!), nor is it clear what they mean [4]. Second, the automatic preference shows up for most people, even in those who consciously express no race preferences and even in many black americans.

Now where did this automatic preference come from? It certainly can’t be deliberate attitudes, since the bias shows up in people (including many black americans) who have explicitly anti-racist attitudes. Some suggestions have been made, like they are the residual of previously held explicit attitudes, or the result of a ‘cultural bias’ (whatever that means) [5], but I think a strong, and more likely causal [6], possibility is that that these preferences are the result of systematic exposure to particular associations (i.e that white = good and black = bad). Associations can become established in memory merely by the repeated co-presentation of two things (conditioning), there doesn’t need to be any logical connection between the two. So if on television the adverts for flash cars and happy domestic scenes always feature white folks and the the crime shows more often have black folks as the bad guys you’re going to absorb those associations.

The researchers running the project imply as much in an answer in their FAQ

…it is very possible to possess an automatic preference that you would rather not have (and the researchers who developed this test are convinced that they, too, fall into this category). One solution is to seek experiences that could undo or reverse the patterns of experience that could have created the unwanted preference. But this is not always easy to do. A more practical alternative may be to remain alert to the existence of the undesired preference, recognizing that it may intrude in unwanted fashion into your judgments and actions. Additionally, you may decide to embark on consciously planned actions that can compensate for known unconscious preferences and beliefs.”

(My emphasis).

The interesting thing for me about the hypothesis that these automatic preferences develope from repeated exposure to particular associations is that you do not need to believe the associations on any deliberate level, nor do you need particularly to pay attention to them, all you need to do is to have them as part of your environment. In that way our Implicit Associations reflect a part of our minds which belongs as much to the environment of our experience as to ourselves – and, additionally, is as much common to everyone who has shared our environment as it is unique to our individual minds.

And this relates to advertising. Adverts are ubiquitious. Advertising shapes the statistical content of the stimuli we are exposed too, however much we decide to give ourselves certain experiences. Does the IAT give us a glimpse of the consequences we reap from an unclean mental environment? [7]

This is the business of selling dreams. Success comes to those who ensure that their customers can dream, or at least reach a special state of mind slightly detached from reality, free of obligation to be pleasured and reassured. A company can lure its customers into such a special state only if it understands the customer’s salient psychological traits

From Selling Dreams: How to make any product irresistible, p171 by Gian Luigi Longinotti-Buitoni (with Kip Longinotti-Buitoni)

As well as semiotics and cognitive psychology there is another tool for understanding advertising – neuroscience! Enter neuromarketing [1]. Neuromarketing promises to tell you how your brain responds to branding, or which adverts during the superbowl are most effective (Vaughan did a great job on this one, here, and here), or how alert people are during normal television adverts (“there may well need to be more ads created.” concludes the executive who commissioned the study!)

Neuromarketing leaves people saying things like

But the brain doesn’t lie, and the ad industry is just waking up to the potential of neuroscience. The brain’s seven defined regions – each affecting a different aspect of brain function – literally light up the screen if stimulated. Each one contributes to different cognitive activities; reasoning, analysis, long or short-term memory, high or low involvement processing, emotion, meaning etc.
(Tess Alps, in the Guardian)

The appeal of neuromarketing is the illusion of being able to access some more fundamental explanatory basis for our actions. People may lie to market researchers, or may even deceive themselves, but – we hope – ‘the brain doesn’t lie’. As psychologist and marketing guru Gerald Zaltman said existing methods don’t go nearly far enough in helping [advertisers] move to a closer understanding of their customers [2]

Sadly for marketing science, a straight description of what the brain is doing is of limited use – the marketing implications crucially depend on how you interpret that activity. And the interpretation depends on your theories and assumptions about the mind. If your assumptions are dubious (see the superbowl study) or just wrong (see the Tess Alps quote above) then you’re not going to get anything more than a pseudo-scientific smokescreen.

Perhaps the real appeal of neuromarketing to advertisers is betrayed by this quote from Jonathan Harries, the creative director at advertising agency FCB:

It is very hard for our clients to buy gut feel because every time they approach [a campaign], their jobs are on the line. Neuroscience promises to measure the gut feel, and that is exciting for us. It makes it easier for us to sell what we believe is right [2]

Here’s a way to make people buy more of your stuff – give them fewer options. Douglas Coupland called the bewilderment induced by there being too many choices ‘option paralysis’ (‘Generation X’, 1991). Now social psychologists have caught on (‘When choice is demotivating’, 2000, [1]). Offer shoppers a choice of 24 jams and they are less likely to buy a jar than if offered a choice of 6 jams. Offer students a choice of 6 essays, rather than 30 essays, for extra-credit and more will take up the opportunity if there is less choice of essay titles – and, what is more, they write better essays. Students given a similar choice of free chocolates (a restricted choice compared to an extensive choice) made quicker choices (not too suprising) and were happier with the choices they did make once they had made them.

We probably like to think that we’re too smart to be seduced by such “branding,” but we aren’t. If you ask test participants in a study to explain their preferences in music or art, they’ll come up with some account based on the qualities of the pieces themselves. Yet several studies have demonstrated that “familiarity breeds liking.” If you play snippets of music for people or show them slides of paintings and vary the number of times they hear or see the music and art, on the whole people will rate the familiar things more positively than the unfamiliar ones. The people doing the ratings don’t know that they like one bit of music more than another because its more familiar. Nonetheless, when products are essentially equivalent, people go with what’s familiar, even if it’s only familiar because they know its name from advertising

Barry Schwartz. ‘The Paradox of Choice’ (2004)

I think the essential point is correct, but there is a sort of sneaking condescension here: All of you people (the ‘test participants’) only like the things you like because you’re familiar with them, not because of any rational or emotional affection for them (that’s just ‘some account’). What’s more – we (the psychologists) have done experiments which show (admittedly only in some circumstances) that familiarity leads to liking; and from this we’re prepared to generalise to all other circumstances you’re involved in. I parody, but I’m sure you see what I mean.

The fact that we tend to like the familiar isn’t too surprising. There’s even a good evolutionary reason for preferring what worked before – if it didn’t kill you last time, why risk doing something else this time? The single most useful thing you can measure to predict what someone will do in the future is not what they want to do, nor is it what they say they’ll probably do, nor what their friends and family will do, but simply what they did last time – such is the power of habit (For more on this see Hack #74 in Mind Hacks).

But the interesting thing about advertising and branding is the process of it making something familiar to us and us taking this as an indication of preference. In other words, we don’t properly take into account that the brand is not familiar to us for any good reason.

Psychologically it’s not too surprising that this should happen. The study [1] which revived the subliminal perception field involved this mere exposure effect. Participants were shown meaningless shapes for time-spans below the perceptual threshold and subsequently they preferred those shapes to other not previously displayed shapes – even though they had not consciously perceived either set of shapes before.

However, is there any evidence that this kind of familiarity effect can be shown to compete with, or even over-ride, actual good reasons for liking or disliking a brand? Perhaps people are happy to use a fairly arbitrary guideline (familiarity) for unimportant decisions, or decisions where the choices are all pretty good, but when more is at stake familiarity is relegated down the table of influencing factors?

In the comments to an earlier post on advertising, Helen said

We tend to take in less information than advertisers thought or hoped: generally about three seconds worth. Also the more they try and bombard us the quicker we ‘shut down’….we have become very selective in our information uptake and processing. [Experiments have] also found that products were negatively rated if the advert was particularly intrusive/annoying /or stopped us doing something (eg those pop ups on the internet). Maybe we will have less intrusive but more effective advertising in the future on the basis of this…? Be thankful that right now it may be annoying but that you automatically cut it out after three seconds so has little effect on you.

I think Helen is thinking of this article from New Scientist Is advertising flogging a dead horse? (24 December 2005). Which contains quotes such as

They used a camera embedded in a pair of glasses to record people’s gaze as they glanced at ads during a shopping trip or journey to work. After analysing the recordings and questioning the subjects, they found that most of the ads made no impression at all: only around 1 per cent could be recalled without prompting. It seems that although we may be looking at brands and advertisements all day long, most of the time we’re not taking anything in.

Which makes the dangerous assumption that if you can’t consciously and spontaneously recall information you didn’t absorb it at the time and aren’t affected by it now (there’s an example of an experiment showing otherwise here: music, wine and will).

Later in the article, the corollary of this assumption is explicitly spelt out:

In short, the reason most advertising doesn’t work is that we’re in a chronic state of attentional overload. Unless advertising is presented in a way the brain can absorb, it is simply not seen

Sure, if you want people’s focal attention, their conscious deliberation and their active support then it is going to be harder and harder when they are bombarded by a million different messages and a million different demands on their time. But although adverts may work this way – or some adverts at least – that doesn’t mean that all adverts do. Some kinds of advertising may work better when you’re not paying attention and when you’re not consciously deliberating about the values they are inculcating in you.

You go to the supermarket and stop by some shelves offering French and German wine. You buy a bottle of French wine. After going through the checkout you are asked what made you choose that bottle of wine. You say something like “It was the right price”, or “I liked the label”. Did you notice the French music playing as you took it off the shelf? You probably did. Did it affect your choice of wine? No, you say, it didn’t.

That’s funny because on the days we play French music nearly 80% of people buying wine from those shelves choose French wine, and on the days we play German music the opposite happens

This study was done by Adrian North and colleagues from the University of Leicester [1]. They played traditional French (accordion music) or traditional German (a Bierkeller brass band – oompah music) music at customers and watched the sales of wine from their experimental wine shelves, which contained French and German wine matched for price and flavour. On French music days 77% of the wine sold was French, on German music days 73% was German – in other words, if you took some wine off their shelves you were 3 or 4 times more likely to choose a wine that matched the music than wine that didn’t match the music.

Did people notice the music? Probably in a vague sort of way. But only 1 out of 44 customers who agreed to answer some questions at the checkout spontaneously mentioned it as the reason they bought the wine. When asked specifically if they thought that the music affected their choice 86% said that it didn’t. The behavioural influence of the music was massive, but the customers didn’t notice or believe that it was affecting them. Similar experiments have shown that classical music can make people buy more expensive wine [2], or spend more in restaurants [3].

Is this manipulation? There’s no coercion, all the customers are certainly wine buyers who are probably more or less in the mood to buy some wine. But they have been influenced in what kind of wine they buy and they don’t know that they have.

What would be the effect, I wonder, of having someone stand by the shelves saying to the customers as they passed “Why don’t you buy a French wine today”? My hunch is that you’d make people think about their decision a lot more – just by trying to persuade them you’d turn the decision from a low involvement one into a high involvement one. People would start to discount your suggestion. But the suggestion made by the music doesn’t trigger any kind of monitoring. Instead, the authors of this study believe, it triggers memories associated with the music – preferences and frames of reference. Simply put, hearing the French music activates [4] ideas of ‘Frenchness’ – maybe making customers remember how much they like French wine, or how much they enjoyed their last trip to France. For a decision which people aren’t very involved with, with low costs either way (both the French and German wines are pretty similar, remember, except for their nationality) this is enough to swing the choice.

This priming affect is, I believe, one of the major ways advertising works [5]. Simply by making it more likely for us to remember certain things, we are more likely to make decisions biased in a certain way. There’s no compulsion, nobody has their free-will wrenched from their conscious grip. There’s just an environment shaped a certain way to encourage certain ideas. And how could anything be wrong with that?

Here’s another approach to understanding how adverts work – cognitive psychology, as discussed in this Wired article from 2002 (thanks Lauren!)

You’ll probably not be surprised that I’ve lots of sympathy for experimenal psychology as a method for understanding adverts (as opposed to, say, semiotics). A conventional experimental cognitive psychology approach to understanding something about advertising would be:

1. Have an idea, e.g., I think Factor X makes people buy more stuff
2. Come up with an experiment which involves two situations which are identical except for the presence/absence of Factor X.
3. Include some measure which is a good enouch approximation for the behaviour ‘buying’ (it could be actual purchases, or it could be something like memory for the product, or extent of positive feelings for the product, which we just assume will convert into sales)
4. Do the experiment, write up the results, let the rest of the (psychology) world criticise your experiment
5. Do follow-up experiments to re-test your idea and counter criticisms.

Or something like that anyway. Here’s an example from the Wired article:

One example: At the University of Texas at Austin, cognitive science professor Art Markman gave a group of hungry people a few bites of popcorn. Another group got no food. Then he showed his volunteers pictures of products
