Moreover, one they get into the wrong track, they just dig in deeper and deeper until they've completely lost it. All the while saying how clever and perceptive you are for spotting their fuck ups before getting it wrong again. It seems like if it doesn't work pretty much first time (and to be sure, it does work right first time often enough to activate the "this machine seems like knows its stuff" neurons) you're better off closing it and doing whatever it is yourself. Otherwise, before long you're neck-deep in plausible-sounding bullshit and think it's only ankle deep. But in a field you don't know well, you don't know when you're going below the statistical noise floor into lala land.
