true.
false.

The world is full of truth and fallacy. Our own logic systems work based on these two things.

Joey is sick. He can't afford to go to a doctor, or perhaps he doesn't like doctors.
Joey goes online to look up a cure for his condition, but he can't even describe his condition.
He asks one question, and he learns a billion different cures, most of which have no concrete proof that they actually work. He just wants the true answer, that will work 100% guaranteed. And just as you might expect, most of the "cure" come with a 100% guarantee with your money back (read the small text at the bottom though).

So far I have experienced several reasons fallacies exist.

A) A person with limited information on the subject "feel" they have the true information, and tells others this "feeling of truth" information which is not necessarily true.

B) A person with a lot of information has some investment in his deliberate concealing of the information he does have. So he deliberately advertises an "alternate truth" to protect his investment.

Person A will rant and rave about some natural cure that does more harm than damage. Person B will recommend an over-the-counter drug for the wages his institution receives for that advertisement.

But Joey just wants the truth about his condition.

Suppose there is a 3rd person who by some chance knows the truth and can prove it over and over and over. Person A will call them a liar, and so will person B. Person A and B are devoted to their systems of fallacy, and preach them as a gospel. Any contradiction to their ideas is fallacy.

I see this over and over and over everywhere I go.

I have been guilty of it myself. I have so little information, and I feel my information might be helpful to someone, so I tell them, and perhaps do more harm.

This is why I put my questions up front, and get feedback from those who know what they are doing. But sometimes you run into Person As and Person Bs on the way, which make the process so much harder and complicated.

In one way or another, all people are limited in their knowledge, so at best, everyone is a liar still.

Perhaps I shouldn't be so opinionated and prejudiced. I should be ready to listen, and slow to speak.

I see this in Government, and in the Medical arena, and on Programming forums and in the workplace.

So, until I have some solid 100% verifiable concrete proof, I'd be best just shutting the trap (mouth) and learning something.

Yet I still see one way a person can have solid 100% verifiable concrete proof...
