How easy are you to fool? Andy Nunn, an Australian mentalist and TEDx speaker, has spent more than 25 years studying attention, persuasion, and human behaviour. In this episode, Andy explains why intelligence doesn’t always protect us from bad decisions, how confirmation bias helps us defend our assumptions, and why a nine-year-old can sometimes see through a trick more clearly than an engineer
Andy Nunn shares his Catch, Challenge, Change framework for solo business owners, reflects on the emotional pressure of working alone, and explores how AI, deepfakes, scams, and “ultra-processed information” are making discernment more important than ever
He also offers a clear warning for anyone using AI in their business: let it help spark ideas, but don’t hand over your creativity.
Key points
1. Why intelligence doesn’t protect against manipulation
Andy Nunn argues that everyone is influenceable, including people who believe they’re highly sceptical, because algorithms can trigger emotions and shape purchasing decisions 06:04.
Intelligent people can build sophisticated explanations for why their beliefs are correct, making it harder to change their minds 11:00.
Adults often stop investigating once they’ve found a plausible explanation, while children keep asking, “why?” and consider more possibilities 09:47.
Discernment depends on staying open to being wrong, not simply on processing information quickly 10:16.
2. A practical method for challenging business assumptions
Andy Nunn uses the “Catch, Challenge, Change” framework to examine decisions and reduce bias 13:38.
Catch the story you’re telling yourself and identify the assumptions behind it, such as believing a quiet sales period means your website is failing 14:49.
Challenge the assumption by asking what else could be true, including changes in the market or wider economic conditions 15:10.
Change the level of certainty rather than forcing yourself to reverse your opinion completely. Andy Nunn describes moving from 99% certainty to 70% 15:38.
3. The emotional reality of working alone
Leaving employment in 2019 meant Andy Nunn became responsible for every part of the business, with emotional regulation proving especially difficult 12:02.
Quiet periods triggered repeated changes to his website, sales copy, emails and advertising, even when the real cause might simply have been a temporary market slowdown 12:59.
Therapy became a major support, with Andy Nunn working with a psychologist for nearly two years while building the business 23:40.
Reaching out to other performers helped him build a network and realise he didn’t have to do everything alone 24:20.
4. AI, scams and the need for deliberate discernment
Andy Nunn says scams are becoming more convincing, including potential voice or video calls that imitate someone you trust 35:38.
He recommends verification systems such as a private code word for confirming that a caller is genuine 36:26.
AI-generated reports can contain convincing hallucinations and fabricated sources, while people may accept them because of “automation bias” 42:24.
AI can support ideas and administration, but Andy Nunn warns against outsourcing creativity and personal communication, especially early client emails 45:23.
