I've noticed that my own memory of stressful events is far more vivid than my memory of ordinary days, and this makes me wonder if psychology's focus on negative biases is just documenting what we already intuitively know. But here's the thing: cognitive biases like negativity bias or confirmation bias aren't just abstract concepts—they shape real decisions, like why we dwell on one criticism among ten praises. However, I'm not entirely convinced that 'bias' is the right frame, because sometimes what looks like a bias is actually an adaptive response to an uncertain world. Could our so-called biases be rational strategies that just don't fit neatly into laboratory experiments? I lean toward yes, but I'd love to hear why someone might argue they're simply errors in thinking.
