How to Get Started

STEP 1
THE EXPERIENCE (2 minutes)
  1. Have you ever:
  2. - Learned a new word
  3. - Then heard it 3 times that week?
  4. - Bought a car
  5. - Suddenly saw that model everywhere?
  6. - Thought of someone
  7. - Then saw them unexpectedly?
  8. This is Baader-Meinhof Phenomenon
  9. Also called 'frequency illusion'
  10. Feels like spooky coincidence
  11. Actually: cognitive bias
STEP 2
HOW IT WORKS (3 minutes)
  1. Two psychological processes:
  2. Selective Attention:
  3. - Brain filters out most info
  4. - Too much to process everything
  5. - When something becomes relevant
  6. - Brain starts noticing it
  7. - Was always there, you didn't see it
  8. Confirmation Bias:
  9. - Once you notice it
  10. - Each instance confirms pattern
  11. - Brain says 'See? It's everywhere!'
  12. - Ignores times you didn't see it
  13. - Creates illusion of frequency increase
STEP 3
WHY IT EXISTS (2 minutes)
  1. Evolutionary advantage:
  2. - Brain prioritizes relevant information
  3. - Filters out noise
  4. - Focuses on what matters
  5. - Conserves mental energy
  6. Without this:
  7. - Overwhelmed by stimuli
  8. - Can't focus
  9. - Everything seems equally important
  10. With this:
  11. - Can focus on goals
  12. - Learn quickly
  13. - But creates illusions
STEP 4
IMPLICATIONS (3 minutes)
  1. Shows:
  2. - Reality is partly constructed
  3. - Attention shapes perception
  4. - 'Everywhere' might just be 'noticed'
  5. Be aware:
  6. - Coincidences aren't always meaningful
  7. - Frequency might not actually increase
  8. - Your attention changed, not the world
  9. Test it:
  10. - Notice this phenomenon
  11. - You'll start seeing examples everywhere
  12. - That's the phenomenon demonstrating itself!
  13. Meta-experience!

Common Challenges & Solutions

Every beginner faces obstacles. Here's how to overcome them:

⚠️ But things really do seem more frequent
Solution: That's the illusion! Your brain is now NOTICING them more, not that they're occurring more. Like buying a red car and suddenly 'seeing' red cars everywhere—they were always there, you just didn't notice before.
