Any tips/advice on getting better at logical reasoning?

Write more. By that I mean “write a lot”, read what you write and look for the holes. Then rewrite to correct the flaws. Repeat as necessary.

Read Encyclopedia Brown. Work the puzzles in Games magazine. Read Sherlock Holmes. Watch House.

Try not to use your emotional feelings when making a point. It will sound like more of an opinion instead.

Take math subjects. If you work at it, it will train your mind in logical thinking.

Practice challenging everything you think you know. This requires observing your thoughts. So, every time you recognize you’ve arrived at a conclusion or accepted something to be fact, challenge it.

Why?
If this is true, then…
How do I know this?

Take an intro to philosophy course. You will become a master of deductive reasoning, spotting both logical fallacies, and invalid arguments.

Familiarize yourself with some of the most common fallacies. Look for examples of them in arguments made by yourself and other people — even (especially) when you’re inclined to agree with those arguments.

Take a logic and critical reasoning class~ or buy a book to one.
