A ready smile, well-applied eye make-up and a dash of youthful vigour are useful components for a successful run for elected office, according to studies into the nature of trust – the most elusive of modern political traits.
Researchers from Paris universities used an algorithm built upon known facial traits that prompt feelings of trust – such as a smiling mouth or wider eyes – and tested it for accuracy on databases of human faces separately assessed by human volunteers.
They used the algorithm to assess thousands of portraits from the 14th century onwards to conclude that people found prominent figures more trustworthy as centuries passed and societies became more prosperous.
The smile was a key element to winning trust with the depiction of stern, patrician leaders changing with a “smile revolution” in portrait styles in 18th century France, according to the study published on Tuesday.
“If you’re smiling, you have a higher chance of being trusted,” said Lou Safra, one of the researchers.
Which of today’s famous faces does the algorithm trust?
The National asked the academics to use their algorithm to assess the perception of trust in a modern-day group of leaders and influential figures.
The researchers first ran an experiment on photographs of a smiling US Democratic presidential candidate Joe Biden and an unsmiling shot of the incumbent, Donald Trump. The algorithm gave Mr Biden a trustworthy rating while ranking Mr Trump as untrustworthy.
The National sent in a series of photographs which were transplanted on to avatars to evaluate the subjects' level of trustworthiness. The team was then able to rate the following 10 leading figures:
The programme came up with the two most and the two least trustworthy. The results are at the bottom of the article but here you can guess the most trustworthy pair.
The research team said the results would be altered if different pictures were used, and also that women and younger people are more likely to be rated as trustworthy.
Ms Safra said cosmetics that make the eyes appear bigger, and judiciously applied lipstick, could alter one’s appearance sufficiently to make a person appear more trustworthy.
Researchers said the latest study tracked changes in the style of prominent people, who in past centuries wanted to be perceived as unsmilingly steadfast and harsh, to the modern political era, in which many leaders seek public approval at the ballot box.
“If people smile it’s because they want to inspire trust, display co-operative features and show themselves as good co-operators,” Ms Safra said.
The results...
Most trustworthy: Meghan Markle and Emmanuel Macron
Least trustworthy: Pablo Escobar and Vladimir Putin
hall of shame
SUNDERLAND 2002-03
No one has ended a Premier League season quite like Sunderland. They lost each of their final 15 games, taking no points after January. They ended up with 19 in total, sacking managers Peter Reid and Howard Wilkinson and losing 3-1 to Charlton when they scored three own goals in eight minutes.
SUNDERLAND 2005-06
Until Derby came along, Sunderland’s total of 15 points was the Premier League’s record low. They made it until May and their final home game before winning at the Stadium of Light while they lost a joint record 29 of their 38 league games.
HUDDERSFIELD 2018-19
Joined Derby as the only team to be relegated in March. No striker scored until January, while only two players got more assists than goalkeeper Jonas Lossl. The mid-season appointment Jan Siewert was to end his time as Huddersfield manager with a 5.3 per cent win rate.
ASTON VILLA 2015-16
Perhaps the most inexplicably bad season, considering they signed Idrissa Gueye and Adama Traore and still only got 17 points. Villa won their first league game, but none of the next 19. They ended an abominable campaign by taking one point from the last 39 available.
FULHAM 2018-19
Terrible in different ways. Fulham’s total of 26 points is not among the lowest ever but they contrived to get relegated after spending over £100 million (Dh457m) in the transfer market. Much of it went on defenders but they only kept two clean sheets in their first 33 games.
LA LIGA: Sporting Gijon, 13 points in 1997-98.
BUNDESLIGA: Tasmania Berlin, 10 points in 1965-66
