We like to think we're rational. We assume customers and employees are too, and that it's easy to predict what people will do based on what makes sense. Predictably Irrational by Dan Ariely throws that idea out. People are irrational, but in very predictable ways, and once you understand those patterns you can use them to run a better business.
In this book talk, Liz Trotter covers the chapters she found most useful for pricing, customer expectations, honesty, and team culture. She then digs into the chapter that changed the most in her company, which is the one on market norms versus social norms. She shares three real decisions it led to. She stopped offering refunds or discounts after a redo, dropped lockout fees entirely, and rethought how team members are rewarded beyond their paycheck.
If you've ever wondered why customers ask for their money back when that isn't really what they want, why fees can make bad behavior worse, or why a cash bonus is forgotten while a gift is remembered, this one is for you.

Highlights summary
Liz Trotter breaks down Predictably Irrational and the lessons she turned into real policy in her cleaning company. She says she has made more than 20 changes tied to this one book. The biggest takeaway comes from the chapter on market norms versus social norms. Once money enters a relationship, people stop thinking about goodwill and start thinking about what's "fair." When the two compete, money wins.
That principle shaped three decisions in her company. First, when a clean has to be redone, they don't offer refunds or discounts. Customers aren't paying for a clean toilet. They're paying for the experience of coming home to a house they don't have to think about. Putting a dollar figure on that experience turns it into a negotiation the company can't win. Her team fixes the work, owns the mistake, and keeps the conversation about the relationship.
Second, they stopped charging lockout fees. Liz connects this to the book's daycare study, where late pickups increased once parents were fined, because the fine turned lateness into something people could simply pay for. Once her company dropped the fee and built a social expectation around access instead, lockouts among new customers essentially stopped. She also gives an honest warning. Switching existing customers from a fee to goodwill was much harder than expected, because a market norm, once set, is hard to undo.
Third, she rewards team members in ways beyond money. Everyone deserves a living wage, but she argues pay alone doesn't create motivation or loyalty. Purpose, value, and feeling like you matter do. Other quick hits include how premium pricing gets established (the black pearl and Starbucks examples), how expectations shape both customer and employee satisfaction, and a company pledge that team members must memorize before moving from rookie to full team member.
