Knowing is not actually half the battle.
We, humans, are imperfect. And once we know our weakness, we can easily focus and get rid of them. Sounds solid and true. Know the subject you are weak at, focus on it, score better marks.
However, this is not the case always. The most obvious example is showing how our visual system is flawed.
Which of the two circle is bigger? The right one, right? Both are the same size. This illusion is called Ebbinghaus Illusion, named after it’s discoverer. The GIF below shows that the circle are actually of the same size and how the size of their neighbouring circle trick our vision system.
That’s why, after getting to know yourself, forming effective habits is probably a more important part of “the battle” to tackle our flaws.
