Something important to keep in mind when conduction research or gathering evidence is to make sure that your sources are credible. For example, Wikipedia is not always the best source because it can be edited by anyone. also making sure that the sources are up to date is important because like I said earlier, out of date information can ruin your credibility or kairos. Another thing to keep in mind is the audience. Setting up evidence in a way that works with your argument while also is understanding to the listener or reader is very crucial.
When I think of evidence, the first thing that comes to mind is court. This is a big place of evidence and it must be chosen carefully and wisely. Evidence in a trial can be life or death for someone. I have never been on trial so I can't exactly relate to this, but I have seen enough CSI and have a grandpa who was a judge and two lawyer uncles. Because of this, I know that evidence is extremely important.
