What is the difference between affirming the consequent and denying the antecedent?
Affirming the antecedent (or Modus Ponens) involves claiming that the consequent must be true if the antecedent is true. Denying the consequent (or Modus Tollens) involves claiming that the antecedent must be false if the consequent is false. Both of these can be used in a valid argument.

What is a consequent fallacy?

What is consequent in critical thinking?
“Affirming the Consequent” is the name of an invalid conditional argument form. You can think of it as the invalid version of modus ponens.

Why is affirming the consequent not a fallacy of scientific reasoning?
The reason it is a fallacy to use affirming the consequent is just that the argument is deductively invalid. The lesson is this: if you have a true conditional, then you cannot derive the truth-value of the antecedent from the truth of the consequent.
