IQ and SAT stats do not strongly correlate with performance anyway.
The fact that SAT scores correlate poorly with workplace success is a red herring -- SAT scores were never supposed to predict workplace success.
Edit: I'm not attempting to justify low grades. Just curious if that could be a valid corollary (not sure if I'm using that word correctly).
I'd assume that it would correlate pretty well to the success of corporate workers.
Incorrect.
Ultimately, I think experience matters more, but there's a whole other section on the app for "What have you built?" and another one for "What tools will you use?"
In addition, sometimes the not-as-smart kid who has a good idea and a lot of motivation can accomplish something great.
If you did not spend months working on something, possibly crying at times with frustration and jumping around euphorically when you hit a new milestone, you have not done something with a high level of ability.
If you're looking for ability to find new algorithms and prove their correctness, I probably win. If you're looking for ability to build a robust application (which is a key point to me -- I'm working on online backups, and the central point of backups is that they do NOT lose data, even if hardware failure occurs) I might win. If you're looking for ability to create an engaging Web 2.0 site, I definitely lose.
I'd assume that what YC means by "ability" is "ability to create whatever you've said on the application form that you intend to create" -- which in my case was an efficient, robust, and secure online backup system, but for most applications would be an engaging Web 2.0 site.
EDIT: Incidentally, it didn't even occur to me to mention the Putnam on the YC application form. For the "high level of ability" question I pointed towards my BSDCan'05 paper concerning stealing RSA keys on Intel CPUs with HyperThreading via an architectural side channel.
This is mainly useful in situations optimized for efficiency--think mass inductions, as into the army or college, where individually judging people isn't possible. The army can't send everyone to officer school, and Harvard can't give everyone a one-semester tryout.
This isn't the situation faced by investors, who can devote more time to distinquishing people.
Think of a situation where you show above average ability relatove to someone. The truth is high achievers will continue to do so irespective of field - so if you want to be the best in the startup world try and extrapolate back to comsthing you have achieved.
I am sure a lot of us (not so fortunate ones) realize our best abilities while working on something we really love.
So the best bet would be to describe your abilities relative to the problem you are trying to solve. How are your abilities helping your startup make significant forward progress?
Why is that unfortunate?
If you can't talk about something like that, I don't think you can demonstrate a high level of ability. Otherwise, do something great or work for someone who can.
