Tim Ash is a very interesting guy. He is both an authority on evolutionary psychology and digital marketing, which puts him in pretty rarified air. He is the bestselling author of Unleash Your Primal Brain and Landing Page Optimization (with over 50,000 copies sold worldwide and translated into six languages). He has been identified by Forbes as a Top-10 Online Marketing Expert, and by Entrepreneur Magazine as an Online Marketing Influencer To Watch.

Our conversation with Tim focused on his most recent book, Unleash Your Primal Brain, and addressed a question very central to behavioral science today: What is rational? This led to addressing how biases and heuristics are grounded in important evolutionary foundations. Tim likens the way we talk about biases today as glitches in the matrix when we should be acknowledging them for what they are: important evolutionary tools to help us survive our environments and thrive in our tribes.

We also discussed the importance of culture and its central focus on the way humans learn to be human. A paradox we discussed is that culture is dependent on tribe members passing down the cultural (social) norms to the next generation without interruption, and yet cross-tribal collaboration is what has given us an evolutionary edge. Tim notes, that what we need to do today is to “stretch beyond our current tribes needs to go and make the effort to contact other people that are very different from us.” And the consequences of not doing that, according to Tim, “ …are going to be the ones that are going to bring down the larger society.” Fascinating stuff.

We hope you’ll find this conversation with this insightful researcher and speaker as exciting as we did. And if you do like it, please give us a quick 5-star rating or a two-sentence review. And thank you for listening to Behavioral Grooves.
