πŸš€ Introduction

  • Evolutionary psychology helps explain a lot, making sense of our observations.
  • But! (Yes, there's a but) There are criticisms we need to know.

i Battle of the brains massive modularity vs. neuroplasticity 🧠

  • Evolutionary psychology assumes our mind is built of modules shaped by evolution.
  • Module, huh? πŸ€” Think about your phone's apps. Each app (module) has a specific function.
  • Twist: Our brains can change (neuroplasticity). So, where do the module boundaries go?
  • Real-world example: Some monkeys have a "snake alarm" in their brains - a special module that detects snakes. It's so specialized, even monkeys who've never seen a snake react to it!
  • Dilemma: While specialized modules (like snake alarms) are believable, the idea of a full modular brain is controversial.

ii A walk down memory earth? speculations about the environment 🌍

  • For a trait to evolve, it adapts to an environment.
  • Problem: Our knowledge about early human environments is like swiss cheese - full of holes!
  • 🌴 For instance: Were our ancestors always near trees or did they migrate frequently? Each scenario affects how traits might've evolved.

iii Testing, 1, 2, 3 testability πŸ“š

  • Some say evolutionary explanations can't be tested easily.
  • Critics argue that we can make up stories (called ad hoc fallacies) about anything.
  • Example: Explaining being kind by saying it helps our family genes, but being selfish helps our own genes.
  • Yet, not all evolutionary theories are just "stories". Some researchers actually set and test predictions!
