Dual coding theory = Why video is #1

Justin Vajko • July 26, 2026

Your brain has a secret.

(and it’s why video works so well in marketing)


Your brain learns best when it gets 2 signals at once.


It's called dual coding theory.


When you hear something & see something at the same time, you create 2 mental files instead of

1.


Double the files = double the chance you’re going to remember, understand, and use that concept later.


(it’s why Ivy League students put such a huge emphasis on going to lectures. it’s way more effective than just reading the textbook by yourself)


Video is such a powerful tool because you’re not just reading somebody’s ideas from a LinkedIn post OR hearing someone’s hot takes on a podcast without seeing their face.


You’re hearing them & seeing them at the same time.


Your brain is taking in their tone, their confidence, and mannerisms.


Everything you’d be taking note of if you met them in person and were deciding: “Hey, is this person trustworthy? Are they legit?”


The science is clear.


If you’re running a business and trying to build trust on LinkedIn, you’ve got to turn on the camera and talk.


Dual coding: Use your face & your voice.


Trust travels faster that way.

Justin takes a seat with RC Victorino to deconstruct why so much B2B content feels the same in this day and age and what it takes to create something people actually want to pay attention to. They dig into how editorial judgment, internal data, and AI can work together without turning your content into another version of what everyone else is already saying. ----- RC Victorino is a brand and content leader at BuildOps who started his career covering small towns for weekly newspapers in New Hampshire — the day before 9/11. That journalism instinct eventually pulled him into B2B tech, where he's spent nearly twenty years trying to get marketers to stop overengineering everything. He believes the best marketing should make someone feel something, not just click something.
