I used to think exactly like this. I'll tell you what helped me.
1. Remember that you also say or believe wrong things quite often. Do people regularly get upset about it and call you out? Or do they give you grace because they care about you whether you're factually right or wrong? You'll be much happier if you learn some intellectual humility. Even the smartest people aren't right all the time (or even 90% of it).
2. Go to therapy. Learn how to practice intellectual flexibility, graciousness, and humility. Find out if you might have OCPD or be on the autism spectrum (not saying you come across that way, but it's worth discussing). It sounds like you, your wife, or both would be miserable with you constantly looking down on her and being irritated. She certainly deserves better than that.
3. Ask yourself whether you'd rather be right all the time or you'd rather have healthy, fulfilling relationships. You generally can't have both.
I am (much) smarter than the average person and almost never feel the urge to call someone stupid anymore or correct them when they're wrong. Most people are much smarter than you think because you're judging them on a scale you've put yourself at the top of.
I'm also much smarter than average, and it used to bother me.
I agree with your call to patience. In some way, we can see intelligence, and general wisdom as two axis.
Beyond patience, consider working on your compassion. You could try meditation, walks and any number of strategies, but foremost, you need to consider all those around us as worthwhile, regardless of their skills, intelligence, wisdom or anything else.
It is up to you to see beyond the superficial, and work your gifts for the benefit of those around you. If you mix your intelligence with compassion, you should be able to make others come to your view.
This is going to be hard to believe, but something that really helped me understand the diversity of what being "right" means is listening to old episodes of This American Life.
There are lots of stories about a normal person in an unusual situation who ends up behaving "strangely" or making decisions it's hard to understand, or there are stories about people in very normal situations who are just very unusual people.
Either way, you learn that everything is a shade of gray and certainty is the most likely way that someone can be wrong.
