In government, American Presidents are the forty-plus leaders of the United States, since its founding, in the years to follow its 1776 declaration of independence from England, among which, in respect to hmolscience, a significant number stem from the Princeton school of social physics. Notable and or relevant factoids are shown below:

His administration, in 2001, began to limit federal funding to stem cell research in which "the life-and-death decision has already been made", which launched the stem cell controversy about ethics of stem cell research (a separation of church and state issue); the logical objection of which, being underlying Christianity-based, as 1993 NIH researcher turned 2009 NIH head Francis Collins argues, being that certain types of stem cells have a soul; hence it is immoral to use them for research purposes.

44.Barack Obama 75Barack Obama

IQE:135A a quick estimate for IQ was made based on the mean of a number of spurious Internet sources: 110-160 (Ѻ), 120-130 (Ѻ), 130 (Ѻ), 145 (Ѻ); averaged up for secular views employed in politics in respect to religion.
45Donald TrumpDonald Trump
Term: 2017-

In 2013, Trump Tweeted: “Sorry losers and haters, but my I.Q. is one of the highest -and you all know it!” (Ѻ)

“I know some of you may think I’m tough and harsh but actually I’m a very compassionate person (with a very high IQ) and with strong common sense.”
— Donald Trump (2013), Tweet, Apr 21

In 2013, Trump tweeted that his IQ was “much higher” than Barack Obama and George W. Bush. (Ѻ)

In 2015, Trump’s IQ was reported, in an article (Ѻ) by, as being 156 based on the fact that he graduated from Wharton School, that the average student needs an SAT score of 1500 to get in, and that this translates to an IQ of 145 to 149 or 156 as reported. This was reported (Ѻ) by to be a hoax article.

In 2016, based on the previous “hoax IQ”, a presidential IQ chart began making the rounds, in social media, stating something to the affect that Dean Simonton was the one who calculated Trump’s IQ at 156 (Ѻ)(Ѻ) and that his IQ was second highest presidential IQ, below John Q. Adams and above Thomas Jefferson.

In Mar 2017, a poll conducted of 3,000 UK residents ranked Trump second lowest in intelligence, above George W. Bush, and ranked Obama first in intelligence, among 30 most talked about public figures on (Ѻ)

In 2017, Jordan Peterson, who thinks his own IQ is in “excess of 150”, stated, in interview (Ѻ), that the “a 160 IQ estimate” for Donald Trump is “too high”, but crouched his statement by noting that being a business mogul, a successful reality show producer, and president does take some level of multifaceted intelligence.


Religious affiliation
Nearly all US presidents, in belief system, have been characterized as being adherents to Christianity in religious belief, with the exceptions of four who have been said to have had some type of atheism association or were nonreligious or with no religious affiliation: Thomas Jefferson, and as others have argued or alleged: Abraham Lincoln, William Taft, and Barack Obama. [5]

Unique among the group is Jefferson, who with his "last persons to know everything", polymath-polyglot, walking encyclopedia status, possessor of a 6,487 book personal library, suffered from the so-called “Henry Adams effect”, described in 1907 by Henry Adams, in his The Education of Henry Adams (see: genius), about how the active mind will always be several generations or millennia ahead of his or her peers, who will be caught in a slower type of mental inertia.
