Nope, not totally sure. I have 12 Super Humans. One applied and 12 applied seem to be the same.
I will time it...
Yup, looks like it does nothing.
15.79 seconds for 1 B Skill points with 1 Super Human, 15.67 with 12 Super Humans. I imagine that the missing 0.12 seconds are due to my finger not being accurate down to an eighth of a second.
