If you rewind the video backward through the century to the mid 1800's you'll discover something interesting.
Take a look at what sort of people listened to William Miller's silly prediction for THE END OF THE WORLD.
Who were these people?

Before we can understand we must realize something about Americans!
America was colonized by religious nuts!
Puritans pissed people off in Europe by being WEIRD.
Holier-than-thou and obsessive compulsive families settled and built cities and lots of churches.
You could be hanged for missing church on Sunday!

Now HOLD THAT THOUGHT.

Less than a century after Americans fought for Independence from England, along comes this war hero, WILLIAM MILLER.
He made a name for himself in the War of 1812 and he was a kind of semi-Apostate from the Baptist church at the time!
But, he figured his military success just HAD TO BE because God was on HIS side. (i.e. the man was delusional.)
_______________________
Just like every subsequent nut-job, Miller sat down with his Bible, a pen, and paper, and asked the same God who gave him military victory
to tell him when JEEZUS was coming back. Gentiles Time: HERE WE COME!!
_______________________
When Miller shared this crackpot wack-job nonsense with his fellow Baptists. . . (wait for it. . . wait for it. . .) most of them thought he was crazy. But, they gave him respect for being a Baptist WAR HERO.
ONLY A FEW in each church thought it was not only plausible, but it sounded ABSOLUTELY TRUE!

I SAID ALL THE ABOVE TO NOW SAY THIS:
_____________________
The Great Disappointment only disappointed his fellow nutjobs. The rest of the maybe-yes, maybe-no followers simply went back to church!
So what?
So, even though Miller's computations were DEAD WRONG (proving himself a False Prophet) enough nut-jobs hung around for a second disappointment.
And a 3rd, 4th, 5th, etc.
Miller gave up, but his fellow crazies WOULD NEVER ADMIT THEY WERE WRONG.
What kind of people do NOT admit they are wrong even when completely disproved?
THAT'S THE ANSWER TO THE TOPIC QUESTION.
People who were able to think they are right and everybody else is wrong CAN COME UP WITH ANYTHING as long as it is contrary to common sense.
Miller begat the 2nd Advent sect.
The 2nd Advent sect begat the Bible Students.
The Bible Students who follow Russell begat a cult led by Rutherford.
Rutherford begat Jehovah's Witnesses.
Jehovah's Witnesses begat CRACKPOT BELIEFS contrary to common sense.
