以色列學者 Yoav Ganzach 的團隊在 <Social Psychological and Personality Science> 期刊發表的論文指出，川普的支持者平均在智力測驗上表現比希拉蕊的支持者差，其差異已經大到可以忽略政黨認同、收入、教育等其他因素：
“Intellectual factors played an important role in the 2016 election,” writes a research team led by Yoav Ganzach of Tel Aviv University. “These results suggest that the 2016 U.S. presidential election had less to do with party affiliation, income, or education, and more to do with basic cognitive ability.”
該研究使用了來自 American National Election Studies 的數據，包含 2012 年的 5,914 名以及 2016 年的 4,271 名調查對象。該調查除了詢問調查對象對當年總統候選人的態度外，還要求他們做一份語言測試，找出與給定的詞句最相近的詞句，作爲智力測量的標準。
Ganzach 發現 2016 年參與者對川普的贊同率與其智力有明顯的負相關 (智力低較容易支持川普)， 2012 年的共和黨參選人 Mitt Romney 的贊同則與智力只有不明顯的負相關。
“Support for Trump was better predicted by lower verbal ability than education or income,” the researchers add. “Our analyses indicate that support for Trump was less about socioeconomic standing, and more about intellect.”
除此研究之外，還有不少研究指出其他可能激發民衆支持川普的因素 (注意 “對經濟情況的焦慮” 已經大致被排除在可能因素外了)：
While economic anxiety has been largely ruled out as a likely explanation, studies have pointed to whites’ fear of declining social status in a rapidly changing society, as well as racist and sexist beliefs, tribalism, possessing an authoritarian mindset, and even being prone to anxiety, and thus susceptible to Trump’s fear-based appeals.
