I personally feel like I understand German-speaking people better the more I study the language.
E.g. my experience was that they are generally good listeners because their language has a sentence structure which forces the listener to wait for the most important information at the end of a sentence.
Bad Denglish to demonstrate:
“I have yesterday night… at the football field… together with friends … (dude get to the point) had a beer”
There’s research to suggest that every language comes with its own specific mode of thinking, which means that for every additional language you pick up, you quite literally gain a new perspective on things in general. I absolutely believe it. It’s also why the party in 1984 was hellbent on using newspeak and outlawing previous languages.
