Research: US Presidential Hopeful Donald Trump Speaks Like An 11-year-old

In the study, 'A Readability Analysis of Campaign Speeches from the 2016 US Presidential Campaign', researchers from Carnegie Mellon University’s Language Technologies Institute (LTI) wanted to establish the reading level of the candidates' speeches. They analysed a number of transcripts for each candidate, including campaign trail speeches, victory speeches and defeat speeches.

The report shows that grammar used by Donald Trump in his speeches as he campaigns to become the Republican presidential candidate corresponds to that used by students aged 11 and under.

The 69-year-old businessman's language tailed his counterparts. Ted Cruz and Marco Rubio - although he has now dropped out of the race - both used grammar corresponding to children aged between 11 and 14 - students between grades six and eight in the US.

But their vocabulary was more advanced and matched students aged between 13 and 16.
