Swedish researchers have discovered that elite soccer players achieve higher scores on certain tests of cognitive ability than their lower division colleagues, and both sets of players do better than the general public!
Over the moon
It seems it’s all about ‘executive functions’ and working memory. Specifically that successful players are able to constantly assess the situation, compare what’s going on with past experiences, create new possibilities and make quick decisions. In short it’s all about making fast decisions under extreme time pressure. Sounds great! Do the England team know about this?
Sick as a parrot
Of course, there may be a physical explanation. Sports psychologists have known for a while that cognitive abilities are correlated with aerobic capacity. So it may just be that footballers, and other athletes, do better simply because they’re fitter. Mind you, if all this is true, it’s a good argument for getting out there and doing a bit more exercise…

A thought experiment for you to try:
Below are a set of numbers. Give a friend five seconds to estimate the answer, without resorting to a calculator.
Set-A 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Here’s another set of numbers. Find a second friend and give them the same instructions.
Set-B 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8
You will find that the second person gives a smaller estimate than the first, and both will be way off the correct answer (which, rather startlingly, is 40,320).
Maybe you’re not surprised that people find it difficult to quickly multiply eight digits, but why the smaller estimate for Set-B? The answer is provided by the only psychologist to win a Nobel prize, Daniel Kahneman. Check out his ground-breaking 1974 article, written with Amos Tversky, in Science magazine.
A little clue: It’s all to do with ‘anchoring’ - a psychological effect that has a profound effect on our decision-making ability, and which in real life trips us up when we try to buy expensive things like houses or cars!

Picture the scene: you’re walking down the street trying to decide where to eat. But it’s early evening and all the restaurants are empty. So you pick what you consider to be the most appealing – you think it has the tastiest menu – and go in. After a while some more people come along and see you sitting at a table. They assume that if you’re in there it must be OK, and enter and sit at another table. Very soon there are lots of people in the restaurant and all the other possible eateries are lagging well behind. This process is called the information cascade.
Information cascades are important in economic psychology as they are used to explain the behaviour of financial markets. That’s because they feed the process of speculation, including frantic buying or selling: bubbles v crashes. Now of course all this starts at a vaguely rational level (remember the restaurant example) but rapidly moves into irrational herd-like behaviour. Thus maybe it’s no accident that we talk about confident or ‘bull’ markets! Although perhaps in reality it’s more cow-like: put your head down, eat the grass and stick with the herd.
The bigger point is that information cascades affect all manner of decision-making. And the movement of the ‘herd’ (group, team, board) can be very difficult to resist, even if you, the individual, recognise it as being irrational. People en masse are easily convinced they are moving in the right direction, and frequently do not stop to ask the obvious question: why are we doing this?
At work this is made worse by the fact that many managers do not know how to probe the thinking of their colleagues. They simply base their understanding on what they assume is going on, and assumptions, as we all know, are often vague and unpredictable beasts. The real trick is to return to the beginning and pose clearly framed questions about the logic of projects and plans, and also to ask questions about the organisation. Not just, ‘why are we doing this?’ but ‘why are we doing it this way?’ So maybe the competency lists that are so beloved of HR professionals should always include the ‘ability to ask good ‘why’ questions’ behaviour…

“A common phenomenon and problem in leadership practice concerns undue reliance on popular fads without sufficient consideration given to the validity of those ideas…” Click on the link below to read a very good review from Amazure Consulting for the evidence on cognitive tests, personality, situational judgement, emotional intelligence and interviews being ‘effective’ predictors of leadership ability.

Graduates! Just another reminder that there’s a multitude of free psychometric tests and questionnaires on the ‘links’ page of my website at:
Also a growing number of other sites that offer free taster tests, for example you will find verbal, numerical and inductive reasoning tests at:

E=MC2 or does it? If you want to try some fantastically hard IQ tests, including the infamous Mega, Titan and Ultra, go here:
Uncommonly difficult IQ Tests
The recommended time for some of these tests is one month. Don’t say you weren’t warned.

Do you remember those computer games that were around in the 1980s? They were text-based, fantasy-like things. I spent many a happy hour slowing down the mainframe ‘looking’ for stuff in a room I couldn’t see, talking to creatures that weren’t there. But, as I have recently been reminded (see link below), this sort of scenario might actually make a good ‘aptitude’ test, especially since it’s now easier to log what people do and to categorise it. I can envisage a business vignette (no elves this time) in which the system monitors the type and quantity of information you seek, the sort of logic you use, any over-riding strategies that appear to govern your behaviour etc – in essence a fusion between traditional psychometrics and what are sometimes called ‘management flight simulators’.

Here are the slides for a recent presentation I gave on preparing for psychometric tests:
Fantastic Test Taking Tactics – How to do Better at Psychometric Tests
It was delivered six times to groups of students preparing for tests. And putting modesty (and alliteration) to one side, was described by one punter as ‘the best lecture he had ever had’, at the university in question…
PS. If you want to know the answers, you’re going to have to ask me!
Slide-9. For the curious, if you guess the answers to 10 questions, in a test with five answer options per question, your chances of picking the correct answers for all the questions are 1 in 10,000,000. Your chances of being struck by lightening are also about 1 in 10,000,000. Guessing is not a good tactic!
