the "we've been wrong before" fallacy

[Xi Shu]

hello, sorry to barge in here but i'm trying to find the name of this fallacy (if it is one),

Quote:It’s possible the problem isn’t as serious as the researchers believe, but I see other reasons for the indifference. We all tend to underestimate the danger from old-fashioned, familiar technologies, particularly when the effects aren’t immediately obvious. Young athletes focus on victory today, not the future damage to their bodies. And if the winner of the Tour de France doesn’t ride a no-nose saddle, then neither will riders who want to look like him.

this is slippery slope

[LMC]

actually it will depend on how big the problem really is , i don't know anything about no-nose saddle or how much winner's cycle decides choice of cycle but if he is trying to make a case against it by taking an extreme case, it will be slippery slope, it may also be a valid argument
