Exploiting rule loopholes in obscure Chinese kickboxing events doesn't constitute much of a "WIN", especially with his subsequent presentation of himself as a "world champion" and "experienced mixed martial artist".
All up, a call for "concrete examples" is exactly what should be going on. From Tim. Not from the unbeliever. The cliche is "the onus of proof is on the believer". Tim's extraordinary claims about drug-free muscle gain, for example, should have had a third-party drug test involved as well as being put in context with his previous and subsequent physique. His extraordinary claims to be a martial arts champion should come with names, dates and number of competitors in his division. Etc.
You have misunderstood me. It doesn't matter if Tim is wrong, if we don't know what is right. If you substantiate your criticisms by finding counter-evidence or disputing his evidence, you add value to the conversation by pointing people in the right direction.
I don't have to find counter-evidence. I just have to ask HIM to show evidence of his extraordinary claims. Arguably, by pointing out how vague his actual evidence is (and putting it in context, e.g. 'world martial arts champion' == 'successful exploiter of loopholes in an obscure Chinese kickboxing event') I'm sort of doing what you say, but the claim that Ferriss should be taken seriously until comprehensively debunked is rubbish. Who has time to wander around debunking every semi-popular crackpot on the web?
All I know is that when Ferriss's claims intersect stuff that I know about I can tell he's full of it. This doesn't raise my level of faith about anything else.
