Is intuition a sense - or is that potentially some people excelling at reading physical cues that 99.999999% of people can't see or relate to what someone is then likely thinking?
When I understand “sense” in this context I’m understanding “sensor.” A sensor is measuring something.
I think the closest I can get to telepathy without it being a completely wild paradigm shift in understanding is if we could implant technology directly into our brains, thus introducing new sensors.
Why would that matter in the slightest, especially given that their purported abilities all seem to flee to another dimension as soon as they're under scientific evaluation?
