Episode notes
Two Brains Process Every Message
- People process messages with two simultaneous systems: an analytical brain and an automatic brain.
- Both systems must agree quickly or the message will be rejected before analysis can follow.
Lead With If → Then → Why
- Use a clear if/then structure so both brains see the cause and effect fast.
- Then explain 'why' in simple terms your audience already understands to make the claim plausible.
Choose Familiar Language Over Mystery
- Use audience language; avoid being mysterious or clever at the cost of clarity.
- If listeners don't understand immediately, research shows they become negatively curious and are repelled.
