Success-biased social learning outperforms trial-and-error in complex tasks

Evidence

When ever the opportunities were made available, students readily used success-biased cultural learning to help design their arrowheads. When cultural information was available, it rapidly led the group to the optimal arrowhead design and was most effective in more complex, more realistic environments. — Joseph Henrich, The Secret of Our Success, 158
