The benefit of randomness reminds me of a study I read of once...the effectiveness of shamanistic rituals for guiding the hunt.

From the archaeological record and parallels/comparisons with recorded historical examples, there was a practice of the shaman heating a large flat bone ( clavicle or pelvic bone) over a fire until it cracked , then interoperating the patterns to code for landmarks etc. The shaman would direct the hunt to a certain area.

The thesis was that this actually resulted in a better success rate. The reason, it was random, it over-rode the tendency to revisit the site of your last success and ensured a better chance of encountering game.

Random works sometimes it seems, and we have a natural tendency to avoid it, we need a hack to fix that.

A recent conversation with a complete stranger where he commented that the big plans, big decisions often pale in importance when viewed in hindsight, the things that had the big life impact going forward were minor happenstance at the time.

I have heard myself echo this same sentiment often over the years, it has certainly been how things have worked out for me over the last 50+ yrs, seems I am not the only one to have noticed. Small stuff can matter a lot
