To be exposed to ideas and observations that may be outside your normal perception.

Forewarning of the issues when it matters, following rational principle, is being forearmed in preparation (should you choose to act on that warning and hedge your survival bets for yourself and loved ones).

There is always an element of chance, but adaptation and flexibility greatly bias towards continued persistence.
