The longer you stay in that loop, the more engaged you become.
And because the answer is in the comments—not the post—you’re encouraged to interact further.
Why the Comments Matter
On platforms like Facebook and Instagram, engagement is everything.
Comments, in particular, signal strong interaction.
By asking users to comment their answer before revealing the solution, these posts achieve several things:
They increase visibility
They create discussion
They extend the time users spend on the post
And importantly, they make you feel involved.
You’re no longer just consuming content—you’re part of it.
The Illusion of Difficulty
Most “brain tests” are not actually difficult in a technical sense.
What makes them tricky is how they’re framed.
They often rely on:
Misleading wording
Hidden assumptions
Visual distractions
Overcomplication
For example, a math puzzle might look like basic arithmetic—but include a subtle twist in order of operations. A visual puzzle might hide shapes in unexpected places.
The challenge isn’t complexity.
It’s perception.
The Role of Cognitive Bias
These puzzles exploit common cognitive biases—patterns in how we think that can lead to errors.
Some of the most relevant include:
1. Anchoring
You fixate on the first interpretation that comes to mind.
2. Overconfidence
You assume your initial answer is correct without checking.
3. Pattern Expectation
You look for familiar structures—even when they’re misleading.
4. Mental Shortcuts
You simplify the problem too quickly, missing key details.
These biases are not flaws—they’re normal parts of human thinking.
But in puzzles, they’re used against you.
The Social Element
One of the reasons these posts spread so quickly is because they’re social by design.
When you comment your answer, you’re doing more than solving a puzzle—you’re entering a shared space of comparison.
You start to notice:
People who agree with you
People who strongly disagree
Explanations that challenge your thinking
This creates a kind of informal debate.
And debate keeps people engaged.
The Psychology of “Don’t Cheat”
Interestingly, the instruction “don’t cheat” can have the opposite effect for some people.
It makes the hidden answer more tempting.
This is related to what psychologists call reactance—a response where people resist being told what to do.
Even in a low-stakes situation like a puzzle, the restriction can increase curiosity.
You think:
“I won’t check… but maybe just a quick look…”
And once you look, the experience changes.
What These Tests Actually Measure
Despite the name “brain test,” these puzzles don’t measure intelligence in any formal sense.
They don’t assess:
