The history of theories of vision contains repeated cases of "extramission" hypotheses, even if you don't believe that 50% of adults now subscribe to a folk "emission" theory of vision.

Most proponents of the theory lived before lasers were invented, though not before the first sunbeams, jets of water, shouts etc.
- buboard 8y agoExtramission is mainly the idea that light illuminates from the eyes though, not that it generates some force, which is the hypothesis in the article.
- theoh 8y agoThe article actually claims that "One of the most common extramission beliefs is that people can “feel” someone else’s gaze as a pressure or heat on the skin." so I don't think your original point (that people were more likely to be tracking gaze to anticipate action) corresponds to the facts. Now, the claim I've quoted could be false, but it's not presented as a hypothesis, but as an explanandum.
