Definition of Factsource: www.merriam-webster.com/dictionary/
- factis something known to happened or to be true or to exist.
- opinionis something believed to have happened or to be true or to exist.
Hence, The difference between fact & opinion is the difference between believing & knowing.
It is important to know the difference between fact and opinion when you're making a decision. When you make decisions, asses others' arguments, and support your own arguments, use facts, as they essentially carry more weights than opinions.
Notice these two examples:
- I really think I should get a promotion. It's about time, and I deserve it. I've earned it.
- I really think I deserve to get a promotion. I've met all my production goals since I've been in here, my evaluations have been excellent, and I was the employee of the month.
As you can see in the second example, facts support the opinion "I deserve to get a promotion".
Furthermore, distinguishing between fact & opinion is important because people will often present their opinion as fact. When you're trying to make big decisions or solve complex problems, you need to know that you're working with evidences rather than emotions. I didn't say that we shouldn't include our emotions in making decisions, but it is more likely to make the correct choice if we base only in facts.
