The essay jumps straight from interview behavior to a decision to not fund, leaving the reader to work out what is the assumption. There is simply no other reason the VC would consider such behavior important.

This would indicate that VCs, on average, make poor judgement on the quality of their investments. The use of arbitrary indicators and qualitative characteristics as a primary decision factor for who they invest in or not would seem to be contributory to their overall poor performance. Perhaps VCs should learn to resist their early (and probably incorrect) assumptions about entrepreneurs based on age, nervousness, or other factors and instead look to the underlying premise of the business and existing capabilities of the management team. Or at least they should realize that they are not particularly good evaluators of those characteristics, based on their past performance, and factor that in accordingly.

Would you? If you've heard that a lot, you probably won't. There's nothing wrong per se - the person could be right, but it's more likely that he is wrong[1]. But something could be said about this person's approach to finding a co-founder, i.e. if he's going about his co-founder search this way, he's probably doing other more serious mistakes other battle-hardened entrepreneurs have learned the hard way.
It's a mental decision-making shortcut. Don't get hung up over little things such as the OP's actual words, like the way the interviewee answers a questions, fidgets, etc. It's just a mental shortcut signal. Sure the OP could be wrong. But he could also be right. How do you know you're not wrong? VCs take a million meetings, make a million decisions, they have LOTS of data to test how well they're doing. They are not random schmucks. Clearly they think about this day and night. Is it possible that they're all wrong and you're right?
Also - I'm not in VC so I can't comment from a position of being an insider, but consider this: if you were a stock trader with an uber stock trading algorithm, would you share it? No. I don't see why VCs would share their "algorithm" either. They're competing with the other VCs for deals in startups, and they each have their secret sauce. They also compete with each other for more investor money (from their LPs).
Lastly, consider this: would any anti-spam vendor fully disclose all their algorithms to detect spam? No, that would be dumb, because then spammers would know exactly how to circumvent them.

Unless maybe the VC is in irrational human being who has biases just like everyone else.
Unless they've actually done studies on whether fidgeting is a good indication of company performance, this statement is ludicrous.
There is a difference between intent to be rational and actually making good decisions, and they don't have to go together.
