I am stuck choosing between two options:
- On the same page (already answered)
- On the same wavelength.
On the surface, they mean pretty much the same thing. However, I make a distinction between the two.
Let's image there are two people, colleagues who work closely together. They agree on certain topic. I would say they are on the same page.
However, if I'm talking about two people who are not aware of eachother; but who (unknowingly) consistently have the same opinion, I would refer to them as being on the same wavelength
To me, being on the same page means you interacted with the other person to make sure you are in sync with one another (= you are in agreement on a topic you have specifically addressed)
Being on the same wavelength, however, describes an innate state of being similar enough to another person, without intentionally having to make sure. (= your mindset/character is similar enough that you would respond similarly to a topic that you haven't experienced yet).
E.g. when we're talking about how twins, even when separated, will make the same decisions consistently, I would call that being on the same wavelength, and not being on the same page (because the twins did not make sure that they made the same choices, it just happened automatically)
If that makes sense.
