The fifth lesson is that Trump will probably continue to prize loyalty above all else in his administration, just as Berlusconi has. Already, Trump has made his three oldest children – who are supposed to run his business during his presidency – key players in his campaign and transition.

Federal law may prohibit Trump from appointing his children to government posts, but they will surely remain at the center of his decision-making. Already, his daughter, Ivanka Trump, and her husband, Jared Kushner, attended Trump’s first meeting with a head of government, Japan’s Shinzo Abe.

The research, designed to determine the intelligence of goats in understanding human social cues, used 35 goats from a goat sanctuary in the United Kingdom.

The researchers presented the herd with images of happy and angry expressions on the same human face (they used a male and female face for different trials), set up on either side of a pen.

The scientists released the goats into the pen from a gate opposite to the location of both images and then timed the goats' interactions with each photograph to determine their preference.
