This article encapsulates the research of Professor Roger Whitaker which suggests that the evolution of the human brain is related to the concept of examining one another and making decisions as to whether we want to help each other or not (Science Daily 2016). The results of a test involving computer simulated 'donation games, ' revealed the complexities of decision-making strategies for humans and established why certain behaviours among individuals start to strengthen over time. The research team concluded that making relative judgments through helping other individuals has been significant for human survival. This new research is critical as it reinforces the social brain hypothesis and offers further insight by suggesting that the challenge of assessing others may have assisted the expansion of the human brain.
