alt Hacker NewsIf shrug-guy is anything like me, he sat there blurting out half-baked ideas and then shooting them down all in his internal monologue, instead of out loud.
For me, I sometimes feel like I'm an old school chess engine, exploring as many possible moves/ideas as I can - as many steps into the future as time allows. Constantly evaluating them based on some known-simplified fitness function usually involving pattern recognition from past experience in similar problems. Eventually I arrive at a place where I'm either confident I know a reasonable way forward (and why some of the obvious ways forward are unlikely to be ideal) - or I've scatter-gun searched all of the quickly available ideas and discovered I have no idea if some of them are good or bad, and I need to do much deeper research and investigation of the problem.
From the outside, that'd look identical to "he could go completely silent, just staring straight ahead with his fingers to his lips"
Sure, but isn't there still an advantage to this? If two people are silently doing this then they don't influence one another as much, helping find a wider range of solutions as well as identify issues with certain solutions that the other might not have seen.
Instead if you're blurting out your thinking more in unison. Naturally you'll stray less, exploring less.
Of course you want collaboration but I find the magic is going back and forth between alone and together. I even find this helpful when just working by myself, stepping away from the problem or context switching, allowing the problem to distill.
