Saw a scientific article, summarized in the blog below

I found it helpful, as I struggle with self-control. And I thought might be helpful for people in this sub, as I was posting it in a few science subs just now.

The short of it is that when self-concept is not clear, people tend to struggle with self-control. Self-concept clarity means having self-related beliefs that are not clear, consistent, or stable. Sort of like not being sure about who you are or changing your self-views often. If you gain more certainty about yourself, maybe having self-control can be easier.
