No-one is ever forcing you to act on a recommendation, this is just another data point to factor into your decision, and more information is always better. Right?
…no. Search costs are a thing that exists. Bad information is worse than no information, so we have a responsibility to find and boost genuine signals, rather than spray out more noise. As Tyler Cowen says, giving someone your favourite book imposes an obligation on them: now they have to read it, or skim enough to convincingly pretend they read it, or at least feel guilty about not having read it.
Format, context, preference, timing: unless all these factors happen to line up, specific recommendations sound a lot like random monkey noises.
I say all of this as a prelude to the fact that I’m about to…lay a bunch of recommendations on you.
