The difficulty comes when someone spends a lot of time professionally explaining complex things to people with unknown and diverse backgrounds. I'm an engineer, and i simply don't take much of anything for granted as "understood". A lot of the time, someone thinks they understand a concept, but have some misunderstanding of some of the basics and it leasts to some drastically different and wrong conclusions.

So, when i explain something, i tend to take a tact of starting on the very basics and showing the extrapolation to the complex. Depending on the specific subject at hand, i often have to stop and back up when the eyes go glassy. 

This might seem condescending or overly detailed at times, but when you're dealing with something where millions of dollars and/or lives are on the line, it's worth it to ensure complete and effective communication.

But this habit becomes difficult to break in a personal setting. So, if someone asks me about something, it's hard for me to not go back to the basics, and the math, which can be worse. That starts to feel like mansplaining a lot, but it's not coming from a point of condescension or belittling, but rather from not wanting to assume you have a firm grip on all the basics.

That sounds a bit different. You could diffuse a situation where it's difficult to turn off in a social setting simply by being aware of it and acknowledging that you have a weird habit that has to do with your career.

Arguably, what makes mansplaining so frustrating in the first place is the total lack of awareness on the offender's part. Being aware that you do that gives you an avenue to be humble about it and maybe even lead to a friendly icebreaker.

So maybe if you start to feel like you're mansplaining, the best move is just to come clean about it and try to laugh it off?
