Why do so many of us prefer our tv volumes to be multiples of 5? Why is there positive bias towards multiples of 5 and 2 in general? Why is there a negative bias towards odd numbers? Like when we try to come up with random numbers we mostly come up with odd numbers. Maths is a concept thats purely created by humans rather than being some natural phenomenon so why do such biases exist?

It’s all based on how we are taught to do math, in base 10. Let’s say you have a volume number show up, 20 is to quiet and 30 is to loud, after having base10 drilled in our heads we subconsciously meet in the middle at 25. My tv doesn’t have numbers that you can easily see so it’s just on a random number at any given time.
