# Test: Spot the Mistake in Less Than 10 Seconds

According to a scientific experiment, when our brain makes decisions, it can take up to 10 seconds before we even become aware of it. For example, when we decide to press a button, we may think we made the choice on the spot. But in reality, our minds have already decided to go for that button seconds before the thought even entered our consciousness.

With that in mind, **Now I’ve Seen Everything **would like to challenge you to solve these visual puzzles in less than 10 seconds. So get those timers ready, and prepare to find the odd one out.
