Some of this is clearly to do with the rise of the geek as a cultural identity, some of it a reaction to the terrible wibbly wobbly irrationality and superstition of the vaccine refusniks, homeopathy proseltysers and the religious fundamentalists.
But let's be honest, little of it has anything to do with actual rational & independent choice.
Most of this - as yesterday's post about Alex & Mike's NYT piece suggested - is likely shaped by people copying each other, not by them making rational decisions based on the evidence. That said, it's a welcome development given the times.
How strongly this shift in attention to science and scientific work compares with the "personal opinions" on abortion and premature birth survival rates that certain UK ministers have expressed (which are clearly contradicted by the evidence).
And in our own part of the forest, with the over claimed certainties and inappropriate precision of so many vendors of what some call "neurononsense", "neuromania" or just plain "brain porn" (aka Neuromarketing).
How delightful then to watch Prof Uta Frith and other neuroscientists on the latest episode of Dara's show (particualry Frith) with their humour, humility and honesty remind us that we're really on at the beginning of understanding how individual brain activity relates to behaviour.
