Observations on body language, behaviour and psychology—finding meaning in the things people reveal without saying a word.

In case you ever believed 911 was an "inside job," watch this...

I went undercover against TikTok's algorithm.

No profile. No follows. No likes. No searches.

I invented a man called Bob and simply watched.

In just 93 minutes, TikTok built him a different version of Britain.

What world is it building for you?

Bob wasn't real.

The world TikTok built around him was.

That's the part I can't stop thinking about.

A young man at airport security looked calm.

Something felt wrong.

Seconds later, he ran.

I learned to spot hidden signals through dangerous dogs, nervous owners—and the occasional bite.

Perhaps intuition is practised observation.

Years ago, I walked into the headquarters of one of North America's most powerful organised crime figures... alone.

The police had one warning:

"He'll probably shoot you."

This is the story of what happened next.

Fear spreads quickly.

But confidence does too.

A calm parent can steady a child.
A composed leader can settle a team.
Even a nervous dog can borrow courage.

Perhaps confidence isn’t something we possess.

Perhaps it’s something we lend.

Imagine creating a brand-new TikTok account with zero personal information.

How long do you think it would take before the algorithm figured out who you are?

I tried it.

The results genuinely surprised me.

[Dan Markham | Hidden Signals @DanMarkhamHS]

People think their phones are listening.

I tested that theory with a blank TikTok account. No profile, likes, searches or location clues—just scrolling.

It still began figuring me out.

Maybe TikTok isn’t listening. Maybe it’s reading us.

[Dan Markham | Hidden Signals @DanMarkhamHS]

TikTok seemed to know me before I’d told it anything.

No follows. No searches. No meaningful viewing history.

Yet within minutes, it was showing me content that felt uncomfortably specific.

I tested what it could infer from almost nothing.

Their new name is much more fitting

Today I was sent the following cool demo:

Two AI agents on a phone call realize they’re both AI and switch to a superior audio signal ggwave

[Elon Musk @elonmusk]

One thing is for sure, it is not boring!

[Dan Markham | Hidden Signals @DanMarkhamHS]

@elonmusk The world is screwed - 😔

[Elon Musk @elonmusk]

This is a real picture

[Piers Morgan @piersmorgan]

I admire a lot of what you do, @elonmusk .. but your vicious attack on President Zelensky last night was incredibly disappointing. Anything negative to say about Vladimir Putin - or is it just the guy whose country he illegally invaded who is the problem?

[CALL TO ACTIVISM @CalltoActivism]

JUST IN: Hillary Clinton ROASTS Trump and posts THIS video where she called Trump, “Putin’s Puppet.”

Hillary was right about everything.

[Piers Morgan @piersmorgan]

The UK didn’t have a general election from 1935-45 because of WW2. How on earth can Ukraine have one now given 6m people left as refugees when the war started, another 3.5m are living under illegal Russian occupation, and the country’s in a state of martial law?
Ridiculous.

@itvnews Shit !!! WW3 is on the cards
