I think this question could be interpreted in many ways, but typically education is correlated with more religious participation.

For Mennonites specifically, education is one of their core values. They also did a study on what matters most to their members that you can check if you’re interested: https://www.mennoniteusa.org/wp-content/uploads/2022/10/MC-USA-Report-FN-compressed-1.pdf

Personally, I think a lot of their belief system and activism efforts just make sense and appeal based on their own merits.

There are many kinds of Mennonites. Most that I know are pretty scientific and well-educated.
