Seriously... Seven Deadly Psychologies - 7. Sloth
Jan 12, 2024
Joining the conversation are Professor Ian Robertson, a leading neuroscientist known for his insights on motivation, and Dr. Adam Rutherford, a geneticist who challenges oversimplified genetic narratives. They explore the evolutionary roots of sloth and the vital role of rest for cognitive health. Ian uncovers how social status impacts motivation via dopamine receptors, while Adam debunks the 'couch potato gene' myth. Together, they discuss practical strategies to combat apathy and promote healthier, more productive lifestyles.

Episode notes
Rest Powers The Brain
- Rest is essential because the human brain consumes about 20% of our energy and needs downtime to recalibrate.
- Without adequate rest cognitive function degrades and you cannot think straight.
Dopamine Drives Motivation
- Apathy in neurodegenerative disease links to loss of dopamine-producing neurons, reducing motivation and task persistence.
- Restoring activity in certain brain areas can revive motivation, showing neuroscience's role in sloth-like symptoms.
No Simple 'Couch Potato' Gene
- Single-gene explanations for complex behaviours are misleading and overstated by media.
- Behaviour arises from many genes interacting with environment and random factors, not a 'couch potato gene.'
