How findings from psychology can be applied to advertising

March 2017 | Richard Shotton

The theme this month will be how findings from psychology can be applied to advertising. It’s a crucial topic as psychology provides an understanding of why people make the decisions they do.

Pretty relevant to advertising you’d think.

As Rory Sutherland puts it “this subject provides a robust, intellectual link between understanding human nature and knowing how to make money.”

The theories are certainly robust. They’re based on peer reviewed evidence from leading scientists across the world. That makes a change from many of our industry beliefs, which often stem more from what we wish was true, than what actually is.

Fittingly, there’s no single, grand theory underpinning psychology. Instead, there’s a broad collection of biases. This has two benefits. First, it means that whatever brief you’re tackling there’s likely to be a relevant bias you can harness. Second, it avoids the danger of making our tasks fit the solutions we have to hand, rather than the other way round.

Over the next four weeks I’ll be covering a range of topics.

12 Brilliant Behavioural Science Books

9 March 2017

 

This week I’ve shared what I think are some of the best books, blogs and events on the topic. In the following weeks I’ll discuss some broad themes such as why observed data trumps claimed data and why we should give as much weight to target moments as target audiences. I’ll also discuss some of the lesser known biases, as I think too much coverage is given to a small subset of biases, such as social proof and framing.

Finally, I’ll look at the ethics and effectiveness of nudging as there seems to be a backlash to the topic.

Influence

This is one of the classics of social psychology. The first edition was written in 1984 by Robert Cialdini, Professor of Psychology at Arizona State University, it outlines six biases that shape human behaviour, namely: reciprocity, commitment, social proof, authority, liking and scarcity.

Events

If you’re in London there is a huge range of speaking events that are either free or minimal cost.

(As an aside the danger is as these events are free we devalue them… Just as happens here with Joshua Bell, the world famous violinist.)

Although the topics at the first three places below cover a wide range of subjects, behavioural science or psychology speakers are regulars.

Behavioural Boozenomics is a monthly meeting held on the second Monday of each month in the Comedy Pub near Leicester Square dedicated to behavioural science. Check out the speakers here

Finally, on the morning of March 24th, WARC will be hosting a free morning seminar on behavioural science and advertising. I’ll be speaking alongside Mark Earls, author of HERD, Seamus O'Farrell, Colin Strong and Crawford Hollingworth.

 

3 underused biases that affect creative messaging, channel selection, media implementation

16 March 2017

 

One of the appealing aspects of behavioural science is that rather than being a single, over-arching theory, it’s a broad collection of biases. That means it’s flexible enough to be applied to the variety of problems we’re trying to solve for brands.

Despite this, the commentary in advertising has been about the same handful of biases: social proof, loss aversion, framing and the like.

With that in mind I wanted to discuss briefly three underused biases. I’ve chosen a range that reflects the different facets of the APG. One affects creative messaging, another channel selection and the final one media implementation.

Pratfall Effect

A bias that should be considered more often is the pratfall effect. This is the idea that admitting a weakness makes a person, or a brand, more appealing. Elliot Aronson, from the University of California, was the first academic to investigate this.

 

He recorded an actor answering a series of quiz questions. In one strand of the experiment, the actor – armed with the right responses – competently answers 92% of the questions correctly. After the quiz, the actor then pretended to spill a cup of coffee over themselves (a small blunder, or pratfall).

 

The recording was played to a large sample of students, who were then asked how likeable the contestant was. However, Aronson split the students into cells and played them different versions: one with the spillage included and one without. The students found the clumsy contestant more likeable.

The implications for marketing

 

So why do imperfections make people and products more attractive?

 

Everyone assumes that brands are fallible, so if a brand is open about its failings, it can persuade consumers that its weaknesses lie in inconsequential areas. This theory partly explains the success of budget airlines. At launch they openly admitted that the trade-off for cheap prices was a compromised service: no reservations and a small luggage allowance. If they hadn’t admitted as much, consumers may have assumed the cost-cutting had come at the expense of safety.

 

Admitting a weakness is also a tangible demonstration of honesty and, therefore, makes other claims more believable. Three of the most successful ad campaigns ever: “Good things come to those who wait” (Guinness), “Reassuringly expensive” (Stella Artois) and “Naughty but nice” (Lyons cream cakes) all made their core claim more believable by admitting a weakness. Sure, these cream cakes are full of sugar and won’t be good for your figure, but they’re worth it because they taste so good.

 

The principal-agent problem

 

If admitting flaws is an impactful tactic, why do few brands apply it?

 

The rarity is explained by the principal-agent problem: what is in the interest of the brand – the principal – is not in the interest of the marketing manager, the agent. If the campaign flops it might be the end of the brand manager’s career. Imagine explaining to the CEO as sales dive that the key message of your campaign was that the brand was expensive. Even referencing Aronson might not save you.

 

For safe career progression then, this tactic is questionable. However, if you want the best chance of growing your brand, consider revelling in your flaws. It will always be a distinctive approach.

 

For a different take on the pratfall effect – here’s Rory Sutherland:

Overcoming confirmation bias

 

Confirmation bias is the idea that we interpret information through a lens of our feelings for the communicator. This makes it hard to change peoples’ minds. As the legendary stock market investor, Charlie Munger says:

 

"The human mind is a lot like the human egg, in that the human egg has a shut-off device. One sperm gets in, and it shuts down so that the next one can't get in. The human mind has a big tendency of the same sort."

 

That’s a problem for brands trying to convert rejecters. However, research by Leon Festinger, a social psychologist at Stanford University, shows that there are moments when it is easier to overcome confirmation bias.

 

He ran a study with Nathan Macoby, from Harvard University, in which members of a college fraternity were played a recorded argument about the evils of fraternities in an attempt to turn them against the tradition. The students were split into two groups and either listened to the recording with no distractions or whilst being played an entertaining silent film.

 

Interestingly, students were more likely to shift their views when they were partially distracted. Festinger's hypothesis was that the mind is normally adept at coming up with counter-arguments to any persuasive communications. However, distraction reduces the mind's ability to generate these counter-arguments.

 

These findings are interesting as they suggest a counter-intuitive approach for targeting rejecters. Rather than seeking out high-attention environments brands should prioritise moments when the audience is slightly distracted.

 

It seems that one of the most cherished beliefs of media planners, that attention is key, may not be right in all circumstances.

For another angle on this topic read Seducing the Subconscious. Robert Heath’s book outlines how advertisers can avoid activating the brain’s capacity for confirmation bias by not engaging it in logical arguments.

Alternatively, there’s an argument that if it’s so hard to win over rejecters then ignore them and focus elsewhere.

Social proof and TV programme selection

Most people assume that the funniness of an ad is determined solely by the content, but psychologists Yong Zhang and George Zinkan have shown that the social context is important too.

The two University of Houston psychologists recruited 216 people to watch soft drink commercials, either on their own or in groups. They found that ads watched in company were rated as 20% funnier than those viewed alone.

 

The impact of large groups might be due to social proof – this is the idea that people are consciously, or subconsciously, influenced by what others are doing around them. So one person in the group laughing encourages others to laugh.

 

So what can brands learn from the social nature of humour? The main point is that the funniness of an ad is not just a creative issue but also one of media placement. Picking the right moment can increase the impact. One implementational tactic is therefore to run copy in programs or genres which tend to be watched in groups. For example, films, documentaries and news are all around twice as likely to be watched in groups according to Infosys data.

These are just three underused biases. There are plenty of others such as signalling, the Von Restorff effect or moral licensing. Please let me know via twitter (@rshotton) what biases you think could be more used in advertising.

Last week I listed a few great events but, somehow, I forgot to mention the highlight of the year – Nudgestock. A day of Behavioural Science on the South Coast on June 9th organised by Rory Sutherland and Ogilvy Change. Get your ticket here

 

23 March 2017

David Ogilvy famously said, “The trouble with market research is that people don't think how they feel, they don't say what they think and they don't do what they say.” This scepticism towards claimed data is shared by most social psychologists.

The difference between claims and the truth is starkly revealed on dating sites. Look at the graph below from OK Cupid! which shows the distributions of heights of its users. The fact it mirrors the US population, but shifted two inches to the right, suggests that people stretch the truth.

More categorical proof that consumers sometimes lie comes from The National Survey of Sexual Attitudes and Lifestyle (NATSAL), conducted by UCL and the London School of Hygiene and Tropical Medicine. In 2010 the 15,000 strong survey found that British heterosexual women admit to a mean of eight sexual partners, compared to twelve for men. The difference is logically impossible.

All of this goes to show that advertisers trying to understand their customers have a problem: if they listen uncritically to consumers, they’ll be misled.

Contending with confabulation

It’s not just lying that makes claimed data problematic. Sometimes consumers try to be honest but they simply don’t know their motivations.

This can be seen in multiple studies – such as this one run by Adrian North, a psychologist at the University of Leicester. He ran an experiment in the wine aisle of a supermarket that found that background music was the main determinant of the nationality of wine bought by punters.  However, when questioned, hardly anyone attributed their behaviour to such an incidental detail. Have a read about it here…

In this experiment consumers tried to answer honestly, but they didn’t have full introspective insight into their motivations. As the New York University psychologist Jonathan Haidt says, the conscious brain thinks it is the oval office but in reality it is the press office.

The situation is particularly misleading as consumers don’t just pluck claims at random, instead they tend to present an overly logical post-rationalisation of events. Rory Sutherland elaborates here.

So if listening to consumers can be misleading what should you do?

First, don’t take responses at face value. Even though the NATSAL respondents are lying their answers are illuminating. They reveal gender expectations about sex: men tend to exaggerate their promiscuity, while women downplay it. The changing ratio between men and women tells a tale too. In 1990 men claimed to have two and a half times more sexual partners than women, by 2010 the gap had dropped to 50%. Gender expectations are levelling out.

Data are not transparent. They need to be teased, analysed and probed. Interpreting them naively will mislead you. But if you dig further, then insights can be uncovered.

Second, adapt your surveys so that you don’t always ask consumers directly. Instead have a cell approach, in which you randomly allocate participants into a cell. Each cell should ask the question in a slightly different way. By comparing the results you can isolate which incidental details are important.

Here’s a simple survey I ran with the brilliant researcher Jenny Riddell that used a cell approach to understand how our sense of value depends on the time-scale over which it is communicated.

Third, don’t just rely on surveys. Create simple field experiments that test the discrepancy between fact and claim as the basis of your experiment. Here’s an experiment I ran with the excellent Claire Linford that did just that.

This test revealed that consumers’ memories of the prices they paid for items are shaped by the means of payment. This gives brands a strong reason to roll out contactless technology.

Interestingly, if you ever want to question people on the street the best thing is to offer them a £1 scratch card in return. Far more effective than offering them a quid.

Fourth, look to sources other than claimed data. Search data is one such place. Have a look at this site.

All you do is drop a term into the search bar and it will return the most popular search strings that have that term and a question word (e.g. who, what, how, why). By including a question word it strips all the noise out and instead you get a great sense of what people really think about your category.

So to finish, two book recommendations.
