When researching the claim “Men cheat more than women”, I have found it to be true. While this article posted is a more recent study I wanted to look into an older article to note if this issue has been present throughout recent times and not just picked up on within the last couple of years. The article I decided complimented this case best had been from the Institute for Family Studies. From both these articles there's a clear understanding that at early ages, stemming from 18-29 specifically within the IFS study, regardless of gender, both men and women alike are known to have some level of infidelity.
What I enjoyed about this article linked specifically is that they take into account how recent technology has shaped the ways people go about infidelity in the modern day. With them accrediting from a study in Computers in Human behavior study that: "8% to 25% of Tinder users are in a committed relationship while using the app". While the 2018 study couldn't take that into account it's interesting that within both trends as we age there's a spike in infidelity from men whereas women decline.
Something presented within both articles is that potentially either gender may not be entirely honest or complicit to reveal whether if they have or haven't and there isn't a tried and true way to fact check, however from the 2024 article a 2021 study from Health Testing Centers who pooled 441 applicants who admitted to infidelity, "47.7% confessed within the week" to their partners regardless of if it was a man or woman who cheated.
While both articles claim that this shouldn't be a globally accredited fact as it was simply from a pool case study it's interesting that regardless of the times and individuals men were found in both instances to cheat more.
