Assumption expressions, common phrases
Jump to conclusions
To form an opinion or judgment hastily without all the facts.
Example: Don't jump to conclusions before hearing the whole story.

Take something for granted
To expect something to be available or done without showing appreciation or realizing its value.
Example: I took his help for granted, and now I regret not appreciating it enough.
Note: While 'assumption' involves believing something to be true, 'taking something for granted' involves not appreciating or acknowledging something as valuable.

Example: She went ahead with the project under the assumption that funding would be secured.
Note: This phrase highlights acting on a belief without concrete evidence, similar to an assumption but often used in a more deliberate manner.

Note: This phrase directly relates to forming opinions without complete information, similar to the concept of making assumptions in general.
