Hillary Clinton may have lost out to Donald Trump in the 2016 US presidential elections because the Democrats were too willing to welcome others with differing views into their party, a study has found.
However, Democrats' greater inclusiveness and willingness to integrate members of other groups as part of their own meant that they identified more with non-Clinton supporters - weakening party cohesion and leading to an election defeat, researchers said.
"Political group processes had a major influence on the election," said Julie Christian from the University of Birmingham in the UK.
One of the keys to Trump's unexpected campaign success was that Republicans viewed him as truly representative of their group, researchers said.
The study shows that Republicans displayed solidarity only with their own group and held more negative attitudes towards those not supporting their group's values.
This greater solidarity was a factor that may have enabled them to act more as a single entity.
Inclusiveness meant that, rather than members drawing a sense of distinctiveness from their Democrat party affiliation, they gained esteem by integrating others into their party.
This emphasis on the collective approach worked against Clinton by hampering Democrat supporters' ability to perceive her as delivering on and embodying the group's values, said researchers, including those from Claremont McKenna College in the US.
This outcome occurred because the group became too flexible with the inclusion of the opposition, they said.
The absence of endorsement for the leader and the use of this integration strategy worked to undermine the chance of a Democrat win.
"When groups must share a common environment after an election, the Democrats' inclusive approach would probably help to pull competing parties together," said Christian.
"However, a more inclusive approach looking for co-operation before the competition is won results in too much integration and loss of momentum for the group," she said.
The researchers note that the strategy of the Republican group to win the election is not necessarily suited to holding leadership after the election.
Their view is that the strongest option for the Republicans, post-victory, would have been to embrace as many Democrat 'out-group' members as possible to grow their 'in-group'.
