Is there any difference between "changing mind on something" and "changing mind about something"? Are these two expressions interchangeable?
I don't think there's a difference. For example, these two sentences mean the same thing to me:
- After thinking hard, I've changed my mind about applying for that job.
- After thinking hard, I've changed my mind on applying for that job.
I think that technically, "about" could be considered more correct. For example, The Free Dictionary uses this as an example for the idiom "change your mind": "After the interview I completely changed my mind about her abilities."
