But, over time, those who scored high on honesty also behaved badly

Historian Baron John Acton famously declared that 'power tends to corrupt and absolute power corrupts absolutely.'
Now, more than a century after Acton's accusation, scientists have shown that even the most noble lose sight of their values when handed the right to govern.
A series of experiments found that once honest people had tasted power, they couldn't resist rewarding themselves at the expense of others.
In a game, volunteers were given control over pay outs to themselves and their followers. Researchers found that once they tasted power, they couldn't resist rewarding themselves at the expense of others
In the game, they were given complete control over deciding pay outs to themselves and their followers.
The leaders had the choice of making pro or anti-social decisions - the latter resulting in awarding less money to the group but more to the leader's own earnings.
The findings showed those rated as less honest at first exhibited more corrupt behaviour.

FEELINGS OF POWER AFFECT THE BRAIN LIKE COCAINE
The feeling of power has been found to have a similar effect on the brain to cocaine.
It increases the levels of testosterone and its by-product 3-androstanediol in both men and women.
Like cocaine, scientists now believe power can lead to too much dopamine causing more negative effects such as arrogance and impatience.
'One thing that angers me, my children and most people across the world is why do powerful leaders not do more good?' said Professor John Antonakis from the University of Lausanne, Switzerland.
'Is it because of power? Do we really have to worry about this force? Is what Acton said really true?
'Corrupt individuals exhibit moral deterioration by using their power to benefit themselves and, by doing so, cause harm to the greater good.
'Powerful individuals are able to impose their decisions and preferences on weaker individuals.'
In the study, the leader was given a pot of money and allowed to divide it how they liked. The more they took out for themselves, the less was left for their followers.
'The results were clear. Power corrupts. When given more followers and more choices, the leader was more likely to make an anti social decision,' Professor Antonakis said.

'In a way, power is to leaders what taste is to vampires. Once they get a taste of it, they cannot let go. The more followers they had, the more corrupt they became.'
The participants were also given saliva tests which showed anti-social decisions were highest among those with the highest levels of testosterone, the male sex hormone.
'What we observed was real corruption using real stakes. For instance, some participants walked out of the lab with about $100 (£60) in payouts,' Professor Antonakis said.
'They knew if they profited they would harm the public good.'
'We think strong governance mechanisms and strong institutions are the key to keeping leaders in check,' he added.
'Organisations should limit how much leaders can drink from the seductive chalice of power.'
