The Psychology of Snap Judgments

First impressions aren’t just important—they’re everything. Research shows that customers, clients, and even your colleagues are forming opinions about you, your brand, and your business in mere seconds—often before you even get a chance to introduce yourself!

In this episode, Colin Shaw and Professor Ryan Hamilton dive deep into the psychology of first impressions, exploring the fascinating (and slightly terrifying) science behind snap judgments. How fast do customers decide whether they like or trust you? Why do first impressions stick so stubbornly? And most importantly—how can you make sure your business gets it right?

From real-world business insights to slightly embarrassing personal stories (yes, there’s a “matching tie and handkerchief” moment), this episode is packed with actionable takeaways, humor, and behavioral science gold.

If you’ve ever wondered why customers make instant decisions about your brand—and how to make sure those decisions work in your favor—this is an episode you don’t want to miss.

"People decide if they like you before you even open your mouth. Customers do the same thing with your business. And once that first impression is locked in? Good luck changing it." – Colin Shaw

✅ Customers form opinions in seconds. Studies show that people can judge competence, trustworthiness, and likability in as little as 10 seconds—or less!

✅ Your rational brain is slower than your gut. Neuroscience suggests that we make decisions before we consciously think about them—then we just make up a story to justify the decision we already made.

✅ Bad first impressions are a business killer. If your website looks outdated, your store is messy, or your customer service rep is unfriendly—customers won’t stick around to give you a second chance.

✅ The Halo Effect can work for you (or against you). One good first impression can positively color how customers see your entire brand. But a bad one? That impression sticks.

✅ First impressions happen multiple times. The moment a customer sees your ad, lands on your website, calls your contact center, or walks into your store—each moment is a new first impression. Make them count.

✅ Be careful what YOU look for. Your own biases affect how you judge customers, employees, and even your team. If you assume someone is a "bad fit," you’ll find reasons to confirm it—even if it’s not true.
