One thing about mind controlling parasites that's bugging me is that we only ever hear about the extreme cases when it's very visible because the host does something counter intuitive from an evolutionary point of view. But statistically there must be many more cases where the effect of the mind control is just partial, not evolutionary suicide or even beneficial.
How spread is this phenomenon really? How many generations does it take for a parasite to evolve into such spectacular effect? Where are the non spectacular mind controlling parasites and how are they influencing their host?
