Sir David Attenborough is the celebrity consumers would most trust as the figurehead for an advertising campaign, according to a survey commissioned by ad agency and creative content providers Brandpool.
However, it was Katie Price who narrowly beat John Terry and Ashley Cole to be voted the least believable brand ambassador, followed by Amy Winehouse, Heather Mills, Tiger Woods and Tony Blair â€“ the latter raising questions
over Labourâ€™s deployment of its former leader as a â€˜secret weaponâ€™ in the run-up to the election.
The survey flies in the face of the Cebra study published last week by research agency Millward Brown, which indexed the appeal of celebrities in relation to certain brands.
But Brandpoolâ€™s research suggests the popularity of young stars such as David Tennant, Cheryl Cole and David Beckham doesnâ€™t always translate into trust.
The poll saw 46% of respondents name Sir David as one of their top three choices, with Stephen Fry second on 36% and Richard Branson third on 20%.
It was the elder statesmen of British broadcasting who dominated the top 10, with Michael Parkinson, Sir Terry Wogan, Sir David Dimbleby, Jeremy Paxman, Lord Alan Sugar and Jeremy Clarkson also highly rated.
These silver-haired stars were favoured despite almost a third of respondents being under 35. And although an even split of men and women voted, the only female celebrity in the top 10 was The One Show presenter Christine Bleakley.
Commenting on the findings, Professor Cary Cooper CBE, one of the worldâ€™s leading psychologists, said: â€œWe mustnâ€™t confuse popularity with trust â€“ they are fundamentally different.
Anyone can become a celebrity if they have sufficient media exposure. But trust is about credibility and substance, and these come from how people live their lives, what they say and so on. The danger is that brand managers will choose whoever is popular at a given time to front their campaigns.
Prof Cooper, the writer, broadcaster and Professor of Organisational Psychology at Lancaster University Management School, added: â€œWhat this survey reveals is that a septuagenarian could actually hold more appeal for
a teenager than the latest soccer star or X-Factor winner.â€
Asked to choose the three celebrities they would least trust as the face of a brand, 39% of respondents opted for Katie Price. Footballers John Terry and Ashley Cole shared second place with 31% of the votes, indicating the immediate influence of negative publicity.
Amy Winehouse got the thumbs down from 30% of respondents, with Heather Mills next on 29%, while Tiger Woods and Tony Blair shared fifth place with 15% of the votes.
Other notable names in the least trusted 10 were David Beckham, Russell Brand and Cheryl Cole, proving once more that popularity doesnâ€™t automatically generate trust, especially where there might be doubt over the life choices and behaviour of celebrities in private.
Brandpool chairman and creative director John McWilliams said: â€œCelebrity endorsement is a powerful marketing tool that can have a huge influence on perceptions of a brand.
But thereâ€™s no simple formula for success and perhaps the public have more nous than advertisers give them credit for. A lot of thought and emotion goes into decisions about the principles and credibility of people in the public eye, based on the evidence they see before them.
â€œItâ€™s interesting that the majority of the most trusted celebrities are in their fifties and sixties, indicating that it takes many years to build the trust of the public. The reputations of the younger celebrities in the survey seem to be far more sensitive to the ebb and flow of the public mood, often driven by negative stories in the media.â€
