Internet communities depend on just a few people because of the 90-9-1 rule: 90% of people lurk, 9% contribute a little, 1% do a lot. It is true on Reddit, where 25% of the most popular subreddits are administered by 4 people; on Wikipedia (77% is written by 1% of users!) & more

1/ Excited to share a new paper w/ @jpferg @SampsaSamila that tests if female inventors invent for women.

We find that when the lead inventor on a patent is a woman the invention is 25% more likely to address female diseases, conditions, and anatomy.

Toxoplasma (a 🐈 parasite) alters the behavior of infected rats to make them take more risks. It might do the same for founders: students with toxoplasma are 180% more likely start ventures & infected founders have 8% higher revenue on average, but are also more likely to quit.
