99% of people get it wrong… How many holes does this t-shirt really have? 
Visual puzzles are a great way to test your observation skills. At first glance, this image seems very simple: a red t-shirt with several visible holes. However, most people give the wrong answer because they only focus on the front of the garment.
Take a few seconds before reading on… How many holes do you count?
Why is this puzzle so tricky? Our brains tend to count only the most obvious openings. But you have to think about the entire t-shirt:
The neck opening.
Both rounds.
The opening at the bottom of the t-shirt.
The large holes are visible in the fabric.
Upon closer inspection, six holes can be seen in the fabric. Since these holes go all the way through the t-shirt, they are visible through the cardboard placed behind it.
The solution
The calculation is as follows:
1 neck opening.
2 sleeve openings.
1 opening at the bottom of the shirt.
6 holes torn in the fabric.
Total: 10 holes.
This is the answer generally expected for this riddle. Why do so many people answer 6?
Most participants only count the visible tears in the fabric and forget that the regular openings in a shirt are also… holes!
These challenges demonstrate how our brain automatically filters out certain information that would otherwise be obvious.
And what was your first answer before discovering the solution?
