will or would

Hello Scott, and welcome to the forums.

1) Will you marry me? A simple question of fact.

Would you marry me? This has a conditional. Would you marry me if I promised to quit smoking, stop sleeping with your sister, get a good job, etc.

2) Forest means that you don't have to have a high IQ to do good things, and people who are born smart can make really bad decisions about how they act.

(PS - It would be best if you used "you" instead of "u," since this is a forum for learning standard or conversational English, and not text messaging, okay?)

1)

In the 1st, you're  asking about the will/desire of the other person. This is a direct question about his/her being willing/intending to go through the marriage. As GG states, this is about facts.

The 2nd has more doubts, involves more speculation. Just trying to find what the other person thinks about such a development, e.g. "Under various conditions (perhaps none, but ...), do you think that you are interested in marrying me?" Not exactly, but you must know the true meaning of the conditional (which this one is) from your native language.

2)

You're not more intelligent than your actions.
You're as smart as your actions are showing you to be.
