2. Argument From Authority

e.g., President Richard Nixon should be re-elected because he has a secret plan to end the war in Southeast Asia — but because it was secret, there was no way for the electorate to evaluate it on its merits; the argument amounted to trusting him because he was President: a mistake, as it turned out.




Carl Sagan (November 9, 1934–December 20, 1996) was many things — a cosmic sage, voracious reader,

In a chapter titled “The Fine Art of Baloney Detection,” Sagan reflects on the many types of deception to which we’re susceptible — from psychics to religious zealotry to paid product endorsements by scientists, which he held in especially low regard, noting that they “betray con...

Also called the enumeration of favorable circumstances, or as the philosopher Francis Bacon described it, counting the hits and forgetting the misses.

e.g., President Dwight Eisenhower expressing astonishment and alarm on discovering that fully half of all Americans have below average intelligence.

Just as important as learning these helpful tools, however, is unlearning and avoiding the most common pitfalls of common sense. Reminding us of where society is most vulnerable to those, Sagan writes:

A subset of the excluded middle, but so important I’ve pulled it out for special attention.

e.g., Prudently plan for the worst of which a potential military adversary is capable, but thriftily ignore scientific projections on environmental dangers because they’re not “proved.”Or: Attribute the declining life expectancy in the former Soviet Union to the failures of communism many years a...

Latin for “to the man,” attacking the arguer and not the argument.

But the kit, Sagan argues, isn’t merely a tool of science — rather, it contains invaluable tools of healthy skepticism that apply just as elegantly, and just as necessarily, to everyday life. By adopting the kit, we can all shield ourselves against clueless guile and deliberate m...

Also called assuming the answer.

Through their training, scientists are equipped with what Sagan calls a “baloney detection kit” — a set of cognitive tools and techniques that fortify the mind against penetration by falsehoods.

… often to rescue a proposition in deep rhetorical trouble.

A close relative of observational selection.

Latin for “It doesn’t follow”.

Considering only the two extremes in a continuum of intermediate possibilities.

Related to (14) excluded middle.

Caricaturing a position to make it easier to attack.

e.g., A God meting out punishment and reward must exist, because if He didn’t, society would be much more lawless and dangerous — perhaps even ungovernable. Or: The defendant in a widely publicized murder trial must be found guilty; otherwise, it will be an encouragement for other me...

e.g., An amazingly accurate and widely quoted “prophecy” of the assassination attempt on President Reagan is shown on television; but — an important detail — was it recorded before or after the event? Or: These government abuses demand revolution, even if you can’t make an omelette w...

Sagan ends the chapter with a necessary disclaimer:

Sagan admonishes against the 20 most common and perilous of these fallacies of logic and rhetoric— many rooted in our chronic discomfort with ambiguity — with examples of each in action:

e.g., A survey shows that more college graduates are homosexual than those with lesser education; therefore education makes people gay. Or: Andean earthquakes are correlated with closest approaches of the planet Uranus; therefore — despite the absence of any such correlation for the nearer, more ...

But rather than preaching from the ivory tower of self-righteousness, Sagan approaches the subject from the most vulnerable of places — having just lost both of his parents, he reflects on the all too human allure of promises of supernatural reunions in the afterlife, reminding us that fa...

e.g., The separation of powers of the U.S. Constitution specifies that the United States may not conduct a war without a declaration by Congress. On the other hand, Presidents are given control of foreign policy and the conduct of wars, which are potentially powerful tools for getting themselves ...

e.g., What happens when an irresistible force meets an immovable object? But if there is such a thing as an irresistible force there can be no immovable objects, and vice versa.

The claim that whatever has not been proved false must be true, and vice versa.

Latin for “It happened after, so it was caused by”

I will always want to know what is beyond our planet. Hopefully, at some point, humanity will be able to travel and see other worlds.
