As a species, we’re prone to it:
Negative events affect us more than positive ones. We remember them more vividly and they play a larger role in shaping our lives. Farewells, accidents, bad parenting, financial losses and even a random snide comment take up most of our psychic space, leaving little room for compliments or pleasant experiences to help us along life’s challenging path. The staggering human ability to adapt ensures that joy over a salary hike will abate within months, leaving only a benchmark for future raises. We feel pain, but not the absence of it.
Hundreds of scientific studies from around the world confirm our negativity bias: while a good day has no lasting effect on the following day, a bad day carries over. We process negative data faster and more thoroughly than positive data, and they affect us longer. Socially, we invest more in avoiding a bad reputation than in building a good one. Emotionally, we go to greater lengths to avoid a bad mood than to experience a good one. Pessimists tend to assess their health more accurately than optimists. In our era of political correctness, negative remarks stand out and seem more authentic. People – even babies as young as six months old – are quick to spot an angry face in a crowd, but slower to pick out a happy one; in fact, no matter how many smiles we see in that crowd, we will always spot the angry face first.
