That remains to be demonstrated with respect to "HN readers," because the group of people who responded to the online poll are very likely not a representative subset of HN readers in general.
Response groups can number in the millions and still be biased by self-selection. There are well known historical examples taught in any good elementary statistics class.
Even IF the response was just self selection bias, it would still show that NT types that hang out at Hacker News are more likely to take online polls. If the types were completely meaningless, then this wouldn't have happened.

This is far beyond any self selection bias.
