Common Mistakes and Clarifications

Misuse of 'Based on'

Be careful not to confuse 'based on' with statements of fact that stand alone without support. For example:

• Incorrect: "Based on its skeleton, Cooper was 25 meters long."
  This is incorrect because Cooper's length is a fact that does not depend on the skeleton itself.
• Correct: "Based on its skeleton, scientists have confirmed that Cooper was 25 meters long."
  This correct usage shows that the skeleton was the basis for scientists' confirmation of Cooper's length.

Correcting Logical Errors

When using 'based on', make sure that what follows logically depends on the stated reason. For example:

• Incorrect: "Based on the evidence, the defendant was guilty."
  Guilty is a state that exists regardless of the evidence.
• Correct: "Based on the evidence, the jury found the defendant guilty."
  This correctly links the jury's decision to the evidence presented.

Using 'based on' correctly helps in clearly and logically structuring arguments and explanations, effectively linking reasons to conclusions.
