I have a startup. I love startups. So should everybody else love startups too? Not at all.
A more direct question: roughly 50% of people are females. Should 50% of startup founders be female?
I don't think so, but I find it difficult to continue the conversation past this conclusion. The reason I don't think so is that I know that my judgment on how cool startups are doesn't extend to everybody else. I intuitively feel that being a founder involves complex traits and personal decisions that I cannot fathom. To simply say the ratio should be the same sounds wrong. It sounds like the same kind of mental error that makes me want to believe everybody should be in startups. Likewise to say that women should not be in startups sounds wrong also. Or to say startups should have more women in them than men. Each possible conclusion is undefendable.
You could try to attack this problem by taking it the level of personal choices: assuming women are rational actors making informed choices, why do so many choose not to be in startups? Is it the environment? The difference in the sexes? Chemicals in the water?
Of course, that doesn't work, because once you try to start making general assumptions about the behaviors of millions of people you're going to start stereotyping and using guesswork. It can't be helped.
So at the end of the day I understand that other people don't want to be founders. And I accept that. Heck, for all I know the people who are not in startups are the smart ones, and I'm the guy who has something wrong with him. Not only am I not sure how to reasonably investigate this issue, I'm not even sure I have my head screwed on well enough to know what a good or bad outcome is.
I think it's one of those things that you can endlessly argue about, and I choose not to. If folks want to discuss why Person A made her personal decision not to stay in the startup or tech world, we could do that. But when generalizing to all women, and to all startups, in my opinion it's just too much abstraction to be a tractable issue.
