It's not a rational reaction to stop flying on 737 Max, despite the daily news headlines in the New York Times over the last 3 days.

Or, it is a perfectly rational reaction for many people, it's just your theory of rationalism—based on coarse-grained probability of an event ("airlines are safer than ever"), rather than Expected Value or something else—is limited and unrealistic. Like, maybe there's some fancy Nash Equilibrium psycho economic rationality in which the empirically observed behavior is actually rational.
