Discussion on quirky aspects of human thinking.

The rationality of customers and employees

Tomorrow night I will be delivering a presentation on the rationality of customers and employees. It will be discussing the common ways in which both those groups deviate from rationality in their behaviour. It will also explain how their behaviour, while not adhering to strict rationality, is actually super rational. In the process, I will use the […]

Behavioural Economics Answers

The questions posted in the previous blog were designed to highlight the two systems of thought (the intuitive and the rational) that operate in our brain (see references for confirmation of this outlandish statement!) The degree to which an individual monitors their intuitive thoughts with their rational mind is a profound indicator of other significant […]

Behavioural Economics Questions

The following simple questions will provide an indication as to how your decision making can be influenced through implicit assumptions. Taking a few minutes to complete the questions as it will provide you with very powerful insights into how easily conscious thinking can be influenced. 1. A bat and a base-ball cost $1.10 together. The […]

How Not To Use Behavioural Economics

Behavioural economics can provide you with powerful insight into how people make decisions and, by implication, how you can influence their decisions. You don’t need to be an economist to know this, it’s been done for centuries and it’s generally called politics or salesmanship. Knowing how humans make decisions can be incredibly powerful. Then again, […]

What are the Chances: Of a Swine Infestation? Part 1

“The time has come,” The Walrus said, “To speak of many things…” In particular, to talk about the probability that you or I may keel over tomorrow because of ‘the dreaded swine flu’. We, as a species, are absolutely appalling at estimating the probability of highly unlikely events (called ‘long-tailed events – because they occur […]

What are the Chances: Of a Swine Infestation? Part 2

The second reason the world reacted with extreme measures is that our sense of judgement was significantly altered by irrelevant and unrelated information that has absolutely no bearing on the decision at hand. A ‘context’ heuristic. If I was to ask you a question that you didn’t know, like “how many quokka’s live on Rottnest Island?”, then […]

What Are The Chances Of That Happening? Part 3

A great comment on how easily our judgements of risk are influenced: “No passion so effectually robs the mind of all its powers of acting and reasoning as fear … To make anything very terrible, obscurity seems in general to be necessary. When we know the full extent of any danger, when we can accustom […]

Everyone Is Voting YES

Because of the bandwagon effect (discussed in an upcoming blog) having the appearance of winning the debate is just as important as actually winning the debate in the public arena. Studies in the US have found that people who have not yet made up their mind in an election were up to twice as likely […]

The Irrationality of Mothers

With Mothers Day fast approaching, you may be interested in some highly counter-intuitive behavioural economics advice (courtesy of the Atlantic on what kind of gift to buy her.) If you’re planning to give your Mother a voucher then you should probably rethink the time frame of your gift. Research has found that a voucher with a highly […]

What Are The Chances Of That Happening? Part 1

We take insurance for granted, yet it is actually quite a modern concept. It is also one that is particularly influenced by our decision making heuristics. The French mathematician Blaise Pascal attributed the development of a key concept underpinning insurance to a monk at Port‑Royal who said, “fear of harm ought to be proportional not […]
