(Olivier Douliery/pool via Bloomberg News)When Donald Trump visited the CIA over the weekend to make a speech, many commentators noted that his audience clapped and cheered enthusiastically. This isn’t the first time Trump has done thisThis isn’t the first time that Trump has engineered applause. This then means that bee swarms against intruders are shaped by social influence. Imagine that Trump’s crowd at the CIA was composed of a mixture of different individuals, with different attitudes toward Trump. Because human beings are easily socially influenced, the difference between real applause and fake applause is less sharp than you might think.
