Political scientists, including one of Indian-origin, have found empirical support for what they term the US President Donald Trump's "emboldening effect," of normalising expressions of prejudice, including racially inflammatory speech.
The researchers, including Karthick Ramakrishnan from the University of California Riverside in the US, said when Trump formally announced his presidential candidacy in a June 2015 speech, he declared, among other comments, that "when Mexico sends its people, they're not sending their best."
In the years since the election, the researchers said, many have speculated his racially inflammatory speech empowered people with latent prejudices to finally act on them -- a phenomenon known as the "Trump effect."
