The general ideaWhat this talk is not about

There’s a couple of things that I’m NOT going to do:

I Tell you what you should or should not buy, eat, etc.

I Tell you how much stu� you should or should not buy, eat, etc.

I Moralize about the negative externalities of consumer behavior.

I Pitch some food item or diet that will miraculously make you

healther and happier.

I Preach about how you can save the planet by growing tomatoes

on your balcony.

I Tell you to become a penny-pincher.

Let’s take a quiz!Meet Sandra

Sandra loves playing tennis.

She began playing tennis at the age of six. By the time she was

twelve, she had already won several local tennis tournaments. At

�fteen, she began competing nationally, and she entered the junior

top 10 very quickly. When she turned eighteen, she immediately

rose into the adult top 10.

However, even though she loves tennis immensely, Sandra decided

that she doesn’t want to pursue a professional tennis career and

instead get an education.

Cognitive biasesThe way humans think

What the hell is a cognitive bias?

I We make inferences about the world all the time.

I Most of the time, we make those inferences automatically and

without much active reasoning [2, 3, 4].

I In doing so, we rely on cognitive heuristics.I These heuristics are very useful!

I But sometimes, they can be labeled as biases [5], because they

lead us astray...

I We make wrong inferences, and we base decisions on those

inferences.

Cognitive biasesThe way humans think

Cognitive biases make us irrational, in a way.

I Generally, humans aspire to be instrumentally rational.

I We have preferences, and we act so as to achieve what we want

to achieve (“utility maximization”).

I Thus, we want to make rational choices.

I However, it has been recognized for a long time [6] that this

pure rational choice model doesn’t really work in reality.

I People can choose whatever they want in a given situation.

I But you can model the situation in such a way that a desired

Cognitive biasesHow they ma�er for consumers

Marketing is, in this sense, the art of nudging [8, 10].

I Nudging means choice architecture:I People can choose whatever they want in a given situation.

I But you can model the situation in such a way that a desired

outcome becomes more likely.

I This is achieved by exploiting cognitive biases.

I In virtually all consumer decisions, we are deluged with

marketing materials.

I We are nudged quite e�ectively...

I But even without marketing, we are irrational consumers!

I “Self-nudging” is actually something I’m working on.

I Classical nudging is paternalistic [10, 9].

I Self-nudging is not.

I Some ideas for self-nudging:

I An easy one: Before making decisions about food spending,

make sure you are not hungry – hunger will make you more

irrational [23].

I Exploit the status quo bias to your bene�t and adjust default

options.

I For example, don’t sign contracts that automatically renew.

Now what?How to become a less irrational consumer

If you can’t beat ’em, join ’em!

SummaryWhat this was about

Take home messages:

I Our minds make heavy use of cognitive heuristics.

I Oftentimes, these heuristics are unhelpful biases, because they

make us make wrong inferences.

I Cognitive biases are a large part of consumer behavior.

I Thankfully, we are predictably irrational [24].

I Cognitive biases are systematic biases.

I We can do something about them.

I By being more aware of our biases and by nudging ourselves,

we can become more rational consumers.
