Doing what you love works better than average as a method to outsized impact because outsized impact requires neglectedness, and a random walk can find neglectedness better than trend-following. This is the same as hunter gatherers using fortune telling to figure out where to hunt, to prevent over-exploiting, and using fortune telling for self-reflection and problem solving (see yijing less wrong essay). All these are specific cases of the more general decision or game theoretic benefits of randomness.
Legibility, markets, communities Maybe legibility and randomness is the link
Kantu farmers also used randomness to avoid the gamblers fallacy and under diversifying rice harvests. Romans used bird augury. Generally examples of mixed strategies using randomness.
More difficult rituals are also better (as are more expensive statistical analysis computers) since they reduce the temptation to re-run the test and cherry pick results

Unfortunately much of this might be BS lol, see LW post about the secret to our success.
You can also use a coin toss (Llewelyn Moss) as a regret checker
