Why do we pick the safe choice just to avoid feeling regret later?
Sometimes we choose the worse bet on purpose - to dodge a feeling that has not happened yet.
Regret aversion is choosing the option that protects us from anticipated regret, even when another option has the better expected outcome. Before deciding, we picture how bad we will feel if a choice goes wrong, and we weight that imagined regret heavily. The action whose failure we would blame ourselves for hardest is the one we quietly avoid - so we often stick with the default or the familiar to keep our hands clean.
Your phone lags every day. A 4 million VND model would clearly serve you better, but you keep the old one - because if the new phone disappointed you, the regret of having 'wasted' the money would sting more than the daily lag you already accept.
We do not just weigh outcomes - we weigh how much we would blame ourselves, and that tilts us toward the emotionally safe choice over the better one.
Name the regret before you decide. Ask which option has the better odds, not which one would hurt your ego least if it failed - then the imagined regret stops steering you.
Regret aversion: you pick to protect your future self from saying 'I knew I shouldn't have.'
