Intelligence is using what you already know and have at your disposal in order to effectively solve a problem. This means that the quantity of books one person reads doesn't equate, or increase the amount of intelligence a person has. Also, a college degree or the amount of money a person has, is not in any way an indicator of someone's amount of intelligence. The only way to measure the "IQ" of a person is to give the person in question multiple problems from different areas and measure the amount of time needed for the correct answer to be found.
If you find yourself facing an abusive partner, that likes to force you to feel stupid by making fun of you, mock you, or in any other way belittle you especially in front of other people, read on. This can mean that your significant other has confidence issues, or that your partner doesn't trust you, or feels left out in an emotional way. The best action to perform in this situation is to have an open conversation about what is happening in order to achieve a higher level of understanding each other.
