There are kind of two different questions here.
First of all yes, humans are pretty good at telling whether someone is looking them directly in the eyes or not. So if you were to ask someone directly whether you are looking in their eyes or some other part of the face, they would probably be right most of the time.
The second part is whether they would notice it consciously without bring asked. That’s a little trickier. I suspect if you were staring directly at some other part of their face, people might get self conscious (do I have a zit? Is my nose that huge?) But looking at a spot between their eyes, or shiftng your gaze periodically would probably fly under the radar.
Would it blow your mind if I told you all the 2K sports games were released by 2K? 😁
