Human intellectuality and foolishness: The cognitive psychology view

How are our minds and brains constructed?

We, humans, cannot make lightning-fast calculations like computers can. We even often make errors. However, humans are capable of feats that computers cannot accomplish; we demonstrate keen intuition, flexibility, and outstanding creativity. Furthermore, our emotional faculties strengthen the bonds between individuals, and the resulting social cohesion allows us to achieve more than we could if we operated individually.

While such intelligence is present in humans, on the flip-side, we also demonstrate our fair share of silliness. For example, we become enslaved to prejudice, believe in jinxes and other superstitions, continually engage in irrational impulse buying, and succumb to jealousy and bitterness, which can plunge us into an endless negative spiral. However, considering that our mental processes developed over a long span of evolutionary history, our intelligence and silliness may in fact be two sides of the same coin.

In this lab, we focus on these dual aspects of human intelligence, and aim to elucidate the nature of human reasoning, decision making, and problem solving.
