Basically the problem is people saying (not only here) "We cannot measure it so it doesn't exist". But how do we create measurement tools anyway ?
I'll take a common object alcohol-thermometer. We cannot directly see nor measure temperature, only it's effect (alcohol dilating or contracting) Likewise, we cannot see nor measure electricity or magnetic fields. We have seen their effects. So this light be the same with the "non-seen abilites". We haven't percived or understood their effects, so we cannot create appropriate measurement tools.
One thing is sure nevertheless : our body produces a magnetic field that can be measured. Plus, our cardiac rythm changes depending on our emotions. If we have positive emotions (happiness, love...) it will be harmonious. If we have negative emotions (fear, anxiety) it will be chaotic.
I don't have such abilites like TheWiseOne, but I can feel if can trust a person or not. This is not particulatry a gift, but something I have developed over the last years.
So I belive these kind of abilites exist, we just have to be aware of them.
