When you presume something, you make an informed guess based on available evidence. Assuming, however, often involves a leap in judgment without requiring evidence.

"Presume" carries a connotation of audacity or boldness in believing something without complete proof. "Assume" is generally less bold, often used in everyday situations where evidence is not strictly necessary.

Presumptions are often open to being challenged or disproved, given their basis in probabilities. Assumptions, however, are more about accepting a premise at face value, often as a starting point for further reasoning.
