There is no empirical evidence to suggest that ageing in humans has been modified by any means, nor is there evidence that it is even possible to measure biological age. And nothing has been demonstrated to be true when it comes to anti-ageing medicines.
There is no empirical data of which I am aware that says one way or the other we yield credible information from acts of torture. However, coming out of Vietnam, we do have some anecdotal evidence that people will say anything to stop pain.
Thus, in general, in the first instance, the direction of interest in empirical fact will be canalised by the logical structure of the theoretical system.
In so far as such a theory is empirically correct it will also tell us what empirical facts it should be possible to observe in a given set of circumstances.
Now obviously the propositions of the system have reference to matters of empirical fact; if they did not, they could have no claim to be called scientific.
That is, a system starts with a group of interrelated propositions which involve reference to empirical observations within the logical framework of the propositions in question.
The overwhelming empirical evidence of current residence of retirement villages is that they don't go in at early ages. The majority go in middle-to-late 70s.
It should simply be an empirical matter whether the climate is changing or not and whether we're responsible. But the various sides of the debate have now become so tribal that it's no longer a matter of changing our views as more information comes in.
A healthy economics has got to have both conceptual, theoretical research and applied, empirical research.
I'm all for empowerment and education, but the empirical evidence is that it doesn't work. That's why I say make it easy.
