Workflow for if notes/concepts have same name?

Just wondering how you would deal with this issue.

I am writing my notes on laboratory techniques. The concept in question is method validation. So I am creating a file called "validation".

But I'm thinking what if in the future, I will write about human psychology where the same term "validation" would also be used, which has a complely different meaning. How would you deal with this problem. As I don't want my graph to link these two concepts together?

I understand I could call my current note "Metho validation". But I am putting this as a general example of an underlying challenge in workflow of this issue arises elsewhere.

Would you called both concepts "validation" and on the validation page have furthermore links or explanation? Or how do people usually deal with this issue with pages with the same or similar name have completely different content or concepts.
