Can not walk in a straight line with eyes closed

This relates to the bodies general 'wear and tear' most peoples soft tissue structures are not in equal states on both sides of the body. Hips may be mal aligned which would cause one leg to appear longer than the other, in addition muscles may be restricted causing reach on one leg to not be as far as the other. You also may have strength differences in either leg therefore one leg will propell the body further than the other. All of which mean that we can not walk in a straight line without visual correction.

It's not because one leg is longer than the other.
People will also row in a spiral in the mist or the dark.
I guess it is probably to do with being right-or left handed.
Could be checked by letting people of both persuations walk or row under those circumstances and see which way the spiral turns.
If there is a significant difference, it must be strength that causes it.

Here's one way to do it, let your feet find the way.

Anyway - the correction doesn't need to be visual.

Wind direction can give it away - as well as the drone of a motorway in the distance (or the voice of a satnav or echos). Or even the lie of the land - like furrows, a footpath or tightrope.

And even with your eyes closed, you should be able to get a good idea where the sun is.

As stated elsewhere it's not to do with handedness as the same effect applies to right and left handers. You'd expect them to spiral in the opposite direction to one another, but they do not.

So it's always clockwise?
Now that is quite interesting!
Looks like Jack Dee's come up with the right answer,
we all descent from the one ancestor that ran in circles,
not from the ones that ran in a straight line and fell to their doom!

In fact, it's by no means always clockwise, but it's consistently clockwise more often than it's anti-clockwise - and this is true whether the walker be right handed or left handed.

See the thread to which Posital links for more on this, and for mention of the research carried out in the 1920s which is still the main source for the subject.

Yes, one can use tricks (Sun, sounds an adult cannot hear anymore, ...)to avoid the problem. So don't charge people $1 and offer $10 if they can walk in a straight line.

If you are blindfolded, you aren't cheating, and there's no guiding sysyem, then the land may cause overcompensation. You e.g. hit an innocent pebble, but you assume you are close to the rocks you've heard about.

It's almost as hard as guessing weights.
