If I'm reluctantly conceding that this advice isn't always put in practice, then why not? What are people doing in its place? We're all creatures who by nature avoid pain and loss, including the pain of alarming ideas and the loss of ideas that we hold. That's why many people substitute the less risky objective of seeking out the leads which would permit them to retain the ideas they cherish for reasons besides accuracy. They're after information and arguments to give them license to stay put. As commentators have remarked again and again, the longest-lasting fans of the topics or debates of religious apologetics (or the dissenting counter-apologetics) are intent on cheering their side—not on deciding to switch anytime soon.
Their word choices stand out. They ask whether they can believe X without losing respect, or whether they must believe Y. Moreover, they significantly don't ask which idea connects up to the leads with less effort than the others...or which idea introduces fewer shaky speculations than the others. The crux is that their darling idea isn't absurd and it also isn't manifestly contrary to one or more indisputable discoveries. They may still care a bit about its accuracy relative to competing ideas, but by comparison this quality is an afterthought. They're gratified as long as the idea's odds exceed a passable threshold. They can honestly envision that the idea could be valid in some sense. The metaphor isn't searching for a loophole but snatching up every usable shim to fix the loose fit of their idea within the niches that need filling. The undisguised haphazardness of it at least ensures that it's adaptable and versatile.
Of course, at root it's a product of compromise for people who are trying to navigate all the forces which push and pull at them. It soothes them about the lower priority they're consciously or unconsciously assigning to accuracy. By scraping together an adequate collection of leads to make an idea viable, they're informing everyone, including themselves, that their selection of the idea isn't unreasonable. If the pursuit of authenticity were a game, they'd be insisting that their idea isn't out of bounds.
Irritatingly, one strange outcome of their half-cured ignorance might be an overreaction of blind confidence. The brashest of them might be moved to declare that their idea is more than just allowable; it's a first-rate "alternative choice" that's as good or better than any other. By transforming it to a matter of equal preference, they can be shameless about indulging their preference.
In isolated cases it really could be. But the relevant point is that, successful or not, the strategy they used was backwards. They didn't go looking honestly for leads to the top idea. All they wanted was greater license to keep the idea they were already carrying with them while they looked. In effect, thinking in these terms motivates more than a mere bias toward noticing confirmations of their idea: they're sent on the hunt. Needless to say, they can't expect anybody else to be as enchanted by their hunt's predictable findings.
