Someone said the answer to the IQ test grid was B, but it's not — it's D, and here's why:

Each square contains four coloured triangles in each corner (TL, TR, BL, BR), using the same four colours: white, blue, green, pink. No colour repeats in the same position across a row — it's basically like Sudoku but with colours and spatial orientation.

Let’s isolate row 3:

First square: TL: green, TR: pink, BL: white, BR: blue

Second square: TL: blue, TR: white, BL: green, BR: pink

So far, in each position, we’ve already used:

TL: green, blue

TR: pink, white

BL: white, green

BR: blue, pink

That means the third square in the row must use:

TL: pink or white

TR: green or blue

BL: blue or pink

BR: green or white

Option D has:

TL: pink

TR: green

BL: blue

BR: white

Perfectly fills all the missing positions without repeating any colour in the same corner across the row.

Option B fails this — it introduces positional duplicates from earlier squares in that row.

So if you said D by instinct but couldn’t explain why — congrats, you’ve got pre-verbal pattern recognition.
If you said B and tried to argue it… you failed a logic test designed for children and tried to style it out. Pathetic.

You weren’t being tested for IQ. You were being tested for self-awareness.
And you lost.
