       | A bit linkbaity; it's not remote touch per se, but the ability to
       | detect a buried object in sand by touch. The subjects couldn't
       | touch the object directly but could feel where it was through the
       | sand. Which doesn't seem weird or supernatural to me, the way the
       | sand shifts etc will be affected by an object inside of it.

       | So, it's just touch, relayed through grains of sand.

         | Same sentiment. It's still touch through a slightly less solid
         | medium.

       | I mean, feeling sand compress in subtle ways and being able to
       | map that mentally to an object that might be hidden in the sand
       | seems like literally touch plus normal world modelling /
       | reasoning.
       | 
       | Couldn't you describe that effect where you can reliably guess
       | the size and other features of things by sound without seeing
       | them as a seperate sense? Well, it's not, again it's just a combo
       | of a sense plus mental modelling / pattern recognition.

         | That seems like a very strong claim against the paper's
         | results. What makes you think that the study participants
         | located the cube with reasoning, rather than unthinking sense?
         | 
         | I think we can be too quick to write things off as somehow
         | coming from conscious thought when they bypass that part of our
         | minds entirely. I don't form sentences with a rational use of
         | grammar. I don't determine how heavy something is by reasoning
         | about its weight before I pick it up. There is something much
         | more interesting happening cognitively in these cases that we
         | shouldn't dismiss.

       | Damn paywalls, when the material is available from the authors,
       | and in much greater detail.
