The risk of sharks is tempered by our experience with them. Few people swim in deep water beaches (because they have signs saying "Danger! Sharks!") And those that do typically take appropriate precautions and maintain awareness.
Sharks don't want to eat you and do quickly let go of swimmers they attack, but that's irrelevant because the damage has already been done. When I was young, a large amount of education was put into stating that shark attacks were rare, and it's true both in absolute numbers and by comparison with how feared they are. Jaws and knockoffs spread irrational fear in the 70s/80s, and my early 90s childhood came with the counterpressue there, but that counterpressue caused many in my peer group to misunderstand the risks. Shark attacks drop off hard to zero if you're swimming in shallow water. Even at 10 meters, which is not uncommon for surfers, they are a real risk. But surfers spend little time at 10 meters out. All of this forms a balance.
This covers any number of circumstances -- why travel is broadening, why rare / degenerative / mental health conditions are so frustrating to explain to healthcare providers / family / others, trying to communicate specialised knowledge, historical bias, what the old know that the young do not (and rarely, vice versa). Tacit vs. explicit knowledge. Theory vs. experience.
There's probably far better existing terminology than what I've come up with (Hume, Kant, and Berkeley address this, as does Plato, within philosophy). But it's also a major concern in a highly diverse yet tightly interconnected world.
