Research suggests we may be genetically programmed to care about the long-term future

---

Humans may be programmed by evolution to care about the future of the environment, suggests research published today.

Dr Peter Sozou suggests that individuals may have an innate tendency to care about the long-term future of their communities, over timescales much longer than an individual’s lifespan. This in turn may help to explain people’s wish to take action over long-term environmental problems.

The findings are published in the Proceedings of the Royal Society B, in a paper entitled Individual and social discounting in a viscous population.

Dr Sozou, of the University of Warwick’s Medical School and the London School of Economics and Political Science, uses a mathematical model of a population of individuals living in communities with limited migration between them.

The study examines what weight individuals should attach to future benefits. It is shown that the answer depends on whether the future benefits are social benefits for their community or private benefits for themselves. Individuals should be expected to take a long-term view of benefits for their community, but a more short-term view of private benefits to themselves. Humans, like all creatures, generally value a reward today more highly than a reward tomorrow – in other words they discount future benefits. But the model shows that the discount rate is lower for social, rather than individual, benefits.

Dr Sozou said: ‘This analysis shows that the social discount rate is generally lower than the private discount rate. An individual’s valuation of a future benefit to herself is governed by the probability that she will still be alive in future. But she may value future benefits to her community over a timescale considerably longer than her own lifespan.

‘Evolution is driven by competition. Caring about the future of your community makes evolutionary sense to the extent that future members of your community are likely to be your relatives.’

However this evolutionary logic does not apply, at first glance, in the case of a global threat such as climate change where the ‘community’, the planet, is not in competition with other communities. ‘In the absence of this competition’, says Dr Sozou, ‘there is no direct basis for evolution to select behaviours which benefit the planet as a whole, and therefore no evolutionary basis for directly determining a social discount rate for global welfare.’

In which case why do we care at all about the long-term future of humanity? The answer, Dr Sozou suggests, is that we have evolved to value social benefits because in our ancestral environment they tended to deliver local benefits – helping our kin to survive. However in the modern age, it is this biological preference for social good which gives us an interest in the future of the planet: ‘In the modern, global environment, such preferences may cause people to care about global problems such as climate change.

‘This issue is particularly important for economics as it has a bearing on decisions about public investments and environmental protection measures - actions which typically involve paying a cost today in order to produce a public benefit tomorrow.’

1. Because there's so much evidence in our actions?

:shrug:

[hatrack]

2. My thoughts exactly - and they know this because of our behavior?

:wtf:

4. (See my response below.)

You too have bought into a myth about humanity.

See the http://en.wikipedia.org/wiki/Cynicism">evolution of the meaning of "http://en.wikipedia.org/wiki/Cynic">Cynic." (Before following the link, ask yourself what a "cynic" is.)

3. To date, I would dare say, the vast majority has been unaware of our effects on the climate

Today, there are still many who are misinformed.

Once people become aware of the truth of the matter, in my experience at least, they want to do something about it.

No one I know would say, "What do I care, I'll be dead by then."

5. It might be there, but

I think the immediate survival of the tribe is a much stronger instinct.

8. Sure, because if the tribe doesn't survive the immediate future, the distant past is meaningless

So, that's why the economic mess bumped "climate change" back down on many people's list of priorities.

[get the red out]

6. We do cling to whatever gives us comfort though

People seem to absolutely cling to any distortion or outright lie that shelters them from the truth of climate change though.

[OKIsItJustMe]

7. Oh! Absolutely!

The enormity of it is so great, there's a feeling that it simply cannot be true.

Most are still in the http://en.wikipedia.org/wiki/K%C3%BCbler-Ross_model">denial stage. Many are stuck in the second stage. Some are in the fourth stage. Unfortunately, many have stopped at the fifth stage.

It's time to move on to the sixth stage. (Accepting the reality, and doing something about it.)

9. I think the repukes, via inbreeding, have bred that trait out. nt

11. Wait, what?

Is is possible to write an entire paper while drunk?
