Jumping to Conclusions

(also known as: hasty conclusion, hasty decision, leaping to conclusions, specificity)

Description: Drawing a conclusion without taking the needed time to reason through the argument.

Example #1:

That new home looks great!  Let’s buy it!

Explanation: The assumption in this example is that this was a snap decision based on emotion, and the many factors one should consider when making a decision this grand were ignored.  In short, reasoning was abandoned.

Example #2:

It’s getting late, and we still have to decide on the school budget. What do you say we just leave it as is and we can call it a night?

Explanation: It is not reasonable to assume the conclusion that the budget should be left where it is based on the desire to go home.

Exception: There are many times when quick decisions are required, and evidence cannot be fully examined, and in such circumstances, we need to come to the best conclusion we can with the resources we have.

Tip: If anyone gives you an unreasonable timeframe for making a decision, it is almost always an attempt to discourage you from critical thought.  If you cannot have what you feel is a reasonable amount of time to come to a well-reasoned conclusion -- walk away.


This a logical fallacy frequently used on the Internet. No academic sources could be found.

Hello Sir,

Is the following real-life fallacy I will describe an example of a hasty generalization or an example of a hasty conclusion(jumping to conclusions):

There was a teacher I remember who loved the Phantom of the Opera. She loved the 2004 movie, the music from that movie, and the general story. This Wednesday there is going to be a television special dedicated to Andrey Lloyd Webber,who composed the music of the 2004 movie version. I assumed that she would watch this special. I have not spoken to her in years. When telling my sister that this teacher would definetely watch this special she said "Why would you assume that?". I assumed that this teacher would like Webber's entire catalogue or want tro know it simply because she liked his work on the 2004 movie version of The Phantom of the Opera.

Thank you Sir.

No Fallacy, you were simply making an assumption based on many factors. Again, outside of argumentation, fallacies really don't apply.
