Episode 131: Thomas Erikson on Communication & Personality Types - You’re Probably One of THESE People | The Tim Castle Show

Incredible conversation, so much FUN, with Thomas Erikson on the show. His phenomenally exceptional book Surrounded By Idiots and the Surrounded By Series have done very well indeed and for good reason.

Thomas is charming, charismatic and a heck of a lot of fun. We had such a good time recording this. I could do it all over again!

Welcome back to The Tim Castle Show - the podcast where we decode human behaviour, master influence, and learn what it really takes to win in business, negotiation, and life.

Today’s guest is one of the most influential thinkers on human behaviour in the world. His book Surrounded by Idiots has sold 14 million copies globally, been translated into dozens of languages, and completely changed how people understand communication, leadership, relationships, and themselves.

If you’ve ever thought:

  • “Why do people misunderstand me?”
  • “Why do brilliant teams still clash?”
  • Or “Why does this person think so differently to me?”

Then this episode is going to hit you like a lightning bolt.

Thomas Erikson — author, behavioural expert, fantastic key note speaker, and the man who taught the world the colour-coded language of human behaviour.

We’re diving into:

  • Personality types in sales and negotiation
  • Leadership and team dynamics
  • Relationships and parenting
  • And how all of this plays out in a world being reshaped by AI

Buckle up — this one will change the way you see people forever. Grab a fika, stick on the podcast and get ready to blow your mind.

We also did a quick fire. round at the end which is pure gold!
