As long as you are using a reputable dating app, the majority of people you match and chat with are going to be honest, for the most part. They might embellish a bit of information here and there to impress, but, for the most part, they are being honest.
If they are looking for a serious partner, they know that being dishonest about such things as what they do for a living, where they went to school or their childhood is something that the other person will find out in time anyway. It would be to their disadvantage to mislead someone they are getting along with.
If you have had some bad experiences with matches that haven’t been honest with you in the past on dating apps, you shouldn’t take it out on everyone else. This will only make you more and more suspicious of people to the point where you are trying to find things that fit into your belief that they are being dishonest.
Oftentimes, there is really nothing there or it is trivial at best, and you are now losing out on someone who may have been your best match. Just be careful when making these assumptions. They can work against you.
