Not entirely sure what that meant, but if you want to find a more credible source google Hymenoepimecis , which is the name of the wasp. It's true I looked for the most sensationalistic article I could find, but it's still pretty cool even in non-tabloid versions.
It means I lost interest and moved onto something else for now. Maybe later...
Interesting, maybe in the future we can genetically modify parasites to alter exactly those things of our personality that we want to change. It's a freaky and disturbing thought, I know, but also very pragmatic.
see this brings up an interesting aspect about the physical nature/basis of personality.... I so want to say "No, the idea of parasites that "change" personality is nonsense".
Obviously, a parasite could not change a personality directly since personality is supposed to be stable and immutable, in theory. However, if we are to be somewhat materialistic and believe that personality results from internal physiology, then significantly altering the internal physiology can GENERATE a NEW personality, creating the illusion of a "changed " personality.
Parasites change the creatures behavior - personality is something else; its more of a conglomeration imo
