Read it again. That's the wrong conclusion, probably due to an error of omission on the part of the author or proofreader. Remember, libertarians don't like big government.
"The result is that irrationally selected politicians can end up telling us how to make more rational decisions. Frankly, I prefer to take my chances with my prefrontal cortex submit to politicians who will certainly govern with me with their amygdalas."
It makes sense as follows:
"Frankly, I prefer to take my chances with my prefrontal cortex (rather than) submit to politicians who will certainly govern with me with their amygdalas."
Thank you both for your correction! It's easy to misread sometimes, and was past my bedtime.
I appreciate clear thinkers who can catch me when I'm not being one, and who are nice about it!:-)
