Not sure why he said that, left = logical and right = arty, right?

That was the idea... though it is not supported by evidence.

It is though. They have run functional MRI scans on people conducting
various tasks (like whilst playing an instrument) and seen pronounced
levels of activity in just one hemisphere.

Remember, we are talking about 'dominance' here, something 'primarily'
functioning in one hemisphere over the other, not that most things can
*only* exist in one hemisphere or another.

The two hemispheres are different sizes for a start so unless
everything is spread out in the larger one, that would be one physical
indication that the larger one *might* carry (primarily) different or
more functions.

I repeat, observe anyone who has suffered a stroke and see if they
have primarily lost speech or motor-functions and how those roles can
often be recovered to some degree by 're-training' (re-building the
neural networks) in the other, non default / dominant (for that role)
hemisphere.

Still, it is a
good metaphor.

It's a very crude one and doesn't really do it justice because it
doesn't (directly) highlight things like empathy, very much part of
what the metaphor covers / indicates.

See, the likes of Fredxx keep going on about 'improving animal welfare
which is just like Josef Fritzl only raping his daughters monthly
rather than weekly or giving them lighter chains instead of the heavy
ones.

Now, are lighter chains better than heavy ones? Yes, probably, but are
should his daughters be chained up at all, of course not. [1]

The only true / complete / kind way is to not rape them *at all* and
not have them chained up *at all*.

There *is* no right way to do a wrong thing, no matter how you try to
soften it up.

[1] We actively use 'incarceration' as a form of punishment, simply
denying someone their freedom, as in prison, but what have all the
chickens, pigs (especially breeding sows) or feed-lot cattle done to
deserve such treatment and worse, why should any of them have to be
killed, just because they happen to be born the 'wrong' gender (like
male chickens or male dairy calves). It's an immoral solution to an
industrial problem because we are trying to treat individual sentient
beings like a food stuff or food generating machine.
