Question

Scratching often makes more problems than it solves, so why is scratching an instinct?

Is it beneficial in some way or a remnant of something that helped?

Answer 1

Probably to remove anything that gets stuck to our body such as ticks, splinters, etc. Something irritates our skin, we touch it instinctively to remove/analyze whatever is causing it
