The problem arises because we don't have a habit of distinguishing "I believe X because I personally investigated the topic", "I believe X because leading experts in the field, who investigated the topic closely, believe X", and "I believe X because other smart-seeming people believe X".

There are languages, real and artificial, in which every sentence grammatically must contain evidential markers, distinguishing such things as "I experienced this myself", "This is a conclusion I inferred from what I experienced", "I heard this from someone I trust", etc.

Always optional in English, unfortunately. It might be useful to cultivate the habit of at least considering the evidential status of whatever one says, and deciding whether it warrants explicit mention. Linking to sources, like I did above, is one sort of evidential.

I had no idea. That is really interesting. What are some artificial languages that have evidential grammar? I knew lojban had evidentials, but I think they're optional.

Láadan has them.

Láadan has a group of function words called "evidentials" that English doesn't have; many other languages do have them.

An evidential tells you why the speaker feels justified in claiming that the words being said are true.

For example, "wa" means "The reason I claim that what I'm saying is true is that I have perceived it myself" and "wi" means "The reason I claim that what I'm saying is true is because it's self-evident; everybody can perceive that it's true, or everybody is in agreement that it's true."

The evidential will always be the last word in a Láadan sentence, and -- unlike the situation in English -- it's required to be there.

I wonder why the evidential is put last. I would have put it early in the sentence.

This way people have to listen to the entire claim before they can disagree with it.
