    There is evidence that the human brain can detect magnetic fields on an unconscious level, although it’s far from settled science.

    https://www.science.org/content/article/humans-other-animals-may-sense-earth-s-magnetic-field

    I think it is entirely possible that we have vestigial magnetosensitivity from hundreds of millions of years ago. If that is so, however, it gives us the potential to redevelop it in the future.

    There’s also a way to fake it- people have made haptic “compasses,” wearable devices like belts which vibrate north at all times. I remember reading many years ago about the first scientists to develop the technology and the first person (one of the scientists) to try it out, and he said that he was able to know where north was for a long time afterward.

    I should say I was only talking about the first part when I meant faking it. We really don’t know if wearing the device made him temporarily (I think it was temporary) magnetosensitive or if he just got so used to where north was in his daily routines that it was just memory.

      I think we use it, just not consciously. It’s not like knowing where north is helps much, but aligning your mental map of an area means a lot

      Have you ever come out of a forest or something not where you expected, then had a moment of disorientation before everything snaps into place and you realize exactly where you are?

        Agreed. I think when most people hear “able to sense magnetic fields”, they think it means you can always point to North. It’s more like being able to feel temperature or proprioception(your ability to sense where your body is). I think it’s another dataset that gets added to our mental calculations, we just can’t pinpoint that exact “sense” and use it actively.

        I just got lost in a city while using Google Maps giving me walking directions. You are talking to the very wrong guy,

      That would explain my drunk human trick. You can get me drunk, blindfold me, and spin me in circles. I will then unerringly point to North. I always know where North is. Even when I’m rebooting after just waking up.

        By any chance do you have a native Australian background? Apparently they don’t have words for “left” and “right” but instead use cardinal directions, i. e. “My north hand.” They have extremely good spatial navigation skills that are thought to be a result.
