In interactions with others, one finds oneself judging if one is hearing the truth or if we are being lied to. In social interactions, it has been seen that the best approach is to tell the truth no matter what. However, as is the case in most social scenarios, the situation can get very complicated and deciding on truth becomes hard.
An interesting case study is how in some games, like poker, the bluff is built into the game. One needs to decide whether the other player is bluffing or telling the truth. Since the rules of the game are known, deciding on a bluff in such games is relatively less complex. Things are a lot different in real life however.
The most intelligent children are said to be the ones who learn how to lie early on. The sign of maturity is when the person realizes his ability to lie and do other evils, but keeps himself in check and focuses his energy in being a good person. One of the characteristics of a good person include an other-focused mindset. As the ancient Jewish teacher, Hillel, put it when asked to explain the Torah while standing on one foot:
“That which is hateful to you, do not do to your fellow. That is the whole Torah; the rest is the explanation; go and learn.”
