"The Pimp" Misrepresents the Point
Dominic (The Pimp) Connor does a great hatchet job, but clearly isn't reading for meaning, but rather just rebuts points singly without attemption to see what I am really saying.
The reason why the distribution, and not only averages matters is easy to see with a simple example: what if a nation (with a very small probability) were wiped out? The fact that on average you might be better off doesn't mean that you're better off over all.
If you want the maths for it, it's straightforward: it is rational to act to maximise the log of your wealth if you're a gambler. Halving your wealth should be compared fairly with doubling it. If you lose 50%, gaining 50% next time won't put you right. Only for small numbers is averaging a reasonably thing to do.
Risking being wiped out should be done for a higher value, such as liberty, rather than for a form of energy that could easily be substituted.
With regard to risk, I'm not simply arguing that all engineering calculation is useless; clearly if a power station is built, it should be built to high standards. However, human nature is such that such risks are pushed. The safer the system, the more leeway is felt by those who are running the system. Allowing for human psychology, there isn't even proportionality between paper and real risk.
As for Keeping up With the Joneses, Domonic makes out that nuclear power is the only possible source of energy (since he is comparing growth with non-growth). Maybe he himself is the arts graduate in making such ridiculus assumptions.
As for the history, who cares if Benn has supported nuclear power? He's not the reason why it's current government policy to push it regardless. Tony Benn's opinion is frankly an irrelevancy.
