Quite disappointing that the article 'explains' the Nash equilibrium (NE) without going into details of how a NE is reached.

During my econometrics study this explanation helped me to explain it to others without going in to the mathematical details:

- Person A needs to decide what the best strategy is for all strategies of B (circle, on paper, the outcomes for A)

- Person B has to do the same (circle as well)

NE => look for 'box' (ie. outcome) that has two circles (there could be more!)

This leads to (confess, confess).
