Investment Personality Biases

A discussion about how investors need to be aware of their personality biases when making investment decisions, particularly focusing on what types of founders they're naturally drawn to or repelled by.

Key Personality Biases in Investing

• Drawn to high-energy, obsessive founders

  • Slightly extreme personalities
  • Uncomfortable level of ambition
  • Independent mindedness
  • Obsession with their craft

• Repelled by certain traits

  • Dry personalities
  • Lack of sense of humor
  • Enterprise/boring business models
  • Overly systematic/process-oriented approaches

How to Address These Biases

• Identify what you're irrationally drawn to

  • Document personality types that excite you
  • Recognize when you're overvaluing charisma
  • Apply a "discount" after initial excitement

• Identify what you irrationally dislike

  • Notice when you're underpricing opportunities
  • Remember you don't need to be friends with founders
  • Focus on understanding the business, not liking the person

Real Examples of Bias Impact

• High-energy founder bias

  • Can lead to overvaluing personality vs business fundamentals
  • May miss opportunities with less charismatic founders
  • Need to separate entertainment value from business value

• Systematic founder aversion

  • Missing opportunities with methodical operators
  • Undervaluing strong but "boring" businesses
  • Need to recognize value in different personality types

Framework for Better Decision Making

• Document your biases explicitly
• Create a system to counteract natural inclinations
• Separate personal preferences from business evaluation
• Focus on business fundamentals over personality
• Apply consistent evaluation criteria regardless of founder personality
