HOW TO WRITE SMART CHARACTERS (or: how to write witty characters as a non-witty author)
Make them think before they speak
Give them time to plan off-screen
Let them notice small details others ignore
Have them ask the right questions, not just give answers
Let them predict consequences before others do
Give them expertise in one specific area
Have them connect two unrelated ideas
Let other characters seek their advice
Show them changing their strategy when something fails
Have them explain complex ideas simply
Let them win arguments by reframing the problem
Give them moments where they say very little but it matters
EXTRA TIP:
You have a secret weapon. And it's called editing! Real people must respond instantly. But writers get unlimited time to craft the perfect line. So your character doesn't need to be fast. They just need to say the smartest thing eventually.
I hope this helps!
