This takes on a sinister tone in connection with interminable "which X is the best for this project" discussions. Evaluating all Xes would take infinite time because new Xes (JavaScript offshoots, Python package managers, CMSes, IDEs, build systems, you name it) are coming out faster than you can fairly evaluate them, and every person on the project has used at least one X. So the question basically boils down to 1) try Foo because of all the Xes all of us have tried it was the only one which didn't cause manic depression, 2) continue the discussion until the most ruthless/charismatic/stubborn person "wins", or 3) try new shiny Bar, because all the cool kids are using it. I wonder if this is part of the reason so many projects go for the new shiny thing: in a group of reasonable people a lot of the time all of them will agree that all existing solutions suck.
