The Wason Selection Task
There are four cards, a simple rule, and all you've got to do is to work out
which cards you need to turn over to see if the rule has been broken. That's
got to be easy, right? Well maybe, but the Wason Selection Task, as it is called,
is one of the most oft repeated tests of logical reasoning in the world of experimental
psychology. So let's see how you do.
There are three questions to complete, each one associated with a set of four cards.
Here's the first question.
You are a quality control technician working for a card games manufacturer. You
have to ensure that cards have been produced in accordance with the following rule:
If a card has a circle on one side, then it has the colour yellow on the other side.
You already know for certain that every card has a shape on one side and a colour
on the other side. Please indicate, taking this into account, which card or cards
you definitely need to turn over, and only that or those cards, in
order to determine whether the rule is broken in the case of each of the four cards
below. (To indicate that it is necessary to turn over a card, simply "select"
the card by clicking in the little box beneath it.)
After you have made your selection(s), press the Submit button in order to move
onto the second question.

Really Deep Thought
Morality in Europe today is herd animal morality - in other words, as we understand it, merely one type of human morality besides which, before which, and after which many other types, above all higher moralities, are, or ought to be, possible.
