How much do blame and punishment determine the decisions we make?
Scientists have been delving into the depths of our brains to find out the answer to this question, and the results may surprise you.
"We as humans, we have these rules that we sort of abide by in cultures, and if you break the rules there has to be consequences so our brains have evolved to develop some sort of punishment based on the crime that was committed," says nanotech scientist Michelle Dickinson.
She says results could change how we feel about the legal system.
"It's quite interesting because it makes you think about, if you have different judges all over the world, the way that their brain is wired in this prefrontal cortex thing could actually result in different punishments."
