Political power has a similar effect on the brain to cocaine - and it's not surprising that, as the Leveson Inquiry shows, our political leaders are hooked on it, says Dr Ian Robertson.

Democracy, the separation of judicial powers and the free press all evolved for essentially one purpose – to reduce the chance of leaders becoming power addicts. Power changes the brain triggering increased testosterone in both men and women. Testosterone and one of its by-products called 3-androstanediol, are addictive, largely because they increase dopamine in a part of the brain’s reward system called the nucleus accumbens. Cocaine has its effects through this system also, and by hijacking our brain’s reward system, it can give short-term extreme pleasure but leads to long-term addiction, with all that that entails.
Unfettered power has almost identical effects, but in the light of yesterday’s Leveson Inquiry interchanges in London, there seems to be less chance of British government ministers becoming addicted to power. Why? Because, as it appears from the emails released by James Murdoch yesterday, they appeared to be submissive to the all-powerful Murdoch empire, hugely dependent on the support of this organization for their jobs and status, who could swing hundreds of thousands of votes for or against them.
Submissiveness and dominance have their effects on the same reward circuits of the brain as power and cocaine. Baboons low down in the dominance hierarchy have lower levels of dopamine in key brain areas, but if they get ‘promoted’ to a higher position, then dopamine rises accordingly. This makes them more aggressive and sexually active, and in humans similar changes happen when people are given power. What’s more, power also makes people smarter, because dopamine improves the functioning of the brain’s frontal lobes. Conversely, demotion in a hierarchy decreases dopamine levels, increases stress and reduces cognitive function.
But too much power - and hence too much dopamine - can disrupt normal cognition and emotion, leading to gross errors of judgment and imperviousness to risk, not to mention huge egocentricity and lack of empathy for others. The Murdoch empire and its acolytes seem to have got carried away by the power they have wielded over the British political system and the unfettered power they have had - unconstrained by any democratic constraints - has led to the quite extraordinary behaviour and arrogance that has been corporately demonstrated.
We should all be grateful that two of the three power-constraining elements of democracy - the legal system and a free press - have managed to at last reign in some of the power of the Murdoch empire. But it was a close call for both, given the threat to financial viability of the newspaper industry and to the integrity of the police system through the close links between the Murdoch empire and Scotland Yard.
