Questions & Answers

Q: How do emotion and morality influence human decision making?

Emotion and morality play essential roles in human decision making. Emotions can drive our choices, such as falling in love or prioritizing the needs of our children. Moral considerations can also guide decision making, as seen in the case of the Vietnam War, where a single picture influenced the outcome.

Q: How does embodied cognition affect decision making?

Embodied cognition refers to the idea that our physical experiences and sensations influence decision making. For example, if asked to throw a switch and sacrifice one life to save five, most people would do it. However, if asked to physically push a person off a bridge to save five lives, most individuals would hesitate due to the visceral emotional response tied to the action.

Q: How does the evolution of the brain contribute to decision making?

The brain has evolved over millions of years, resulting in different regions responsible for various functions. The orbital frontal cortex, dedicated to social and emotional processing, evolved alongside the lateral frontal cortex, which is involved in cold cognition and programming-like tasks. These two components must work together for effective decision making.

Q: How does brain injury impact decision making?

Brain injuries, particularly to the orbital frontal cortex, can significantly impact decision making. The case of the man with a rod through his orbital frontal cortex in 1848 demonstrated that while his IQ remained intact, his social and emotional abilities were severely impaired. This illustrates the importance of both cognitive and emotional processing in decision making.

Summary & Key Takeaways

• Human decision making is influenced by emotion, morality, and social interaction, which cannot be replicated by computers.

• Emotion plays a significant role in decision making, such as falling in love or prioritizing the needs of a baby.

• Morality can have a profound impact on decision making, as seen in the example of a single picture altering the course of the Vietnam War.
