Pseudoscience is easier to contrive than science, because distracting confrontations with reality — where we cannot control the outcome of the comparison — are more readily avoided. The standards of argument, what passes for evidence, are much more relaxed. In part for these same reasons, it is much easier to present pseudoscience to the general public than science. But this isn’t enough to explain its popularity.

About
Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Pero no sirve de nada tener esos derechos si no se usan: el derecho de libre expresión cuando nadie contradice al gobierno, la libertad de prensa cuando nadie está dispuesto a formular las preguntas importantes, el derecho de reunión cuando no hay protesta, el sufragio universal cuando vota menos de la mitad del electorado, la separación de la Iglesia y el Estado cuando no se repara regularmente el muro que los separa. Por falta de uso, pueden llegar a convertirse en poco más que objetos votivos, pura palabrería patriótica. Los derechos y las libertades o se usan o se pierden.
She was determined to be as tough-minded as possible, without abandoning the sense of wonder that was driving her in the first place.

Those who invalidate reason ought seriously to consider whether they argue against reason with or without reason; if with reason, then they establish the principle that they are laboring to dethrone: but if they argue without reason (which, in order to be consistent with themselves they must do), they are out of reach of rational conviction, nor do they deserve a rational argument.
