Standard deviation. Heisenberg's Uncertainty Principle. The Observer Effect. Are these things confined to scientific research labs or are they prevalent in society at the macroscopic level? How?

In theory (:-)), any rule/law which is applicable on the quantum level should also apply to the 'macroscopic.' 

"And Jesus said to them, Because of your unbelief: for truly I say to you, If you have faith as a grain of mustard seed, you shall say to this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible to you."--Matthew 17:20.

Obviously, to affect a mountain at the quantum level requires a relative tanker-load of faith. :-)

At the science level they are all quantifiable and 'proven' descriptors for specific events. At 'normal people' level they are generalisations that we observe when we want to.

The standard deviation has meaning at the macroscopic level but the other two do not except as in being used as a metaphor or the terms being used wrongly.

The uncertainty principle is quantum only. By measure a subatomic particle's  position we change its momentum. By measuring it's momentum we change its position. Thus we cannot know both at the same time. This does not happen in a macro world.

Not true.

(But I think you missed an important element in my reply. :-))
