[MD] Intention changes physical world (some questions)

[Case]

[David M]
I think your hints about the ability to manipulate
human beings is a fair point and a big concern.
But there is a difference between science and
simply the ability of certain organisations,etc,
to exert their power. But I'm afraid I remain
skeptical about the potential of the so-called
human sciences, because there is too much of
a DQ/SQ mix to be able to model successfully,
but your optimism is an opinion you can adopt & promote.
The jury is still out.
Any other evidence you have in mind?

[Case]
It depends on what you want to model. If you want to sell vacuum cleaners
you can keep knocking on doors until you get a feel for how many you have to
knock on until to make a sale. You could look at collections of salesmen and
compare their averages and look for difference in the force of their
knocking. There are plenty of ways to theorize analysis test and measure
your theories. Even as unpredictable as the daily weather is it settles into
annual and long term patterns and variation in these patterns can also be
studied and measured. It becomes a question of resolution and scale. How
much detail do you need to examine to achieve the level of understanding you
seek.
