About Kai Smith

Most health, psychology, and productivity advice isn't wrong. It's just incomplete.

It cherry-picks a single study, strips away the nuance, and hands you a headline dressed up as wisdom. You follow the advice, it doesn't quite work, and you're left wondering what you missed.

That's the gap I built Kai Smith Insights to close.

Who I Am

I'm a researcher, writer, and entrepreneur obsessed with one question: what does the science actually say, and how do you use it?

My background is in behavioural science, but my curiosity doesn't stay in one lane. I spend my time connecting dots across health, psychology, business, relationships, and learning. Not because those fields are similar, but because the most useful insights usually live at the edges where they overlap.

I believe that good research, clearly explained, can change how you live. Not in a motivational-poster way. In a practical, decision-by-decision way.

What You'll Find Here

Every article on this site starts with peer-reviewed research and ends with something you can actually do. No hype. No pseudoscience. No advice dressed up as science because it sounds smart.

Just clear, honest, evidence-based insights, translated from academic journals into plain language and applied to your real life.

Topics I cover regularly:

• Health and longevity: what the research says about how we sleep, move, eat, and age
• Psychology and behaviour: understanding why we think and act the way we do
• Learning and performance: evidence-based strategies for getting better at things that matter
• Relationships and social dynamics: the science behind how we connect and communicate
• Business and decision-making: applying behavioural science to work and strategy

The Mission

Kai Smith Insights exists to help you make better decisions using the best available science.

The world doesn't need more content. It needs more clarity. My goal is to be the person who reads the research so you don't have to, and then gives you the honest version, not the marketable one.

If you've ever felt overwhelmed by conflicting advice, let down by wellness trends, or suspicious that there's a more grounded way to approach self-improvement, you're in the right place.
