Affirming the consequent is a logical  fallacy involving an incorrect inference  

肯定後件是一種邏輯謬誤，涉及

from a conditional statement. It occurs when one  reason that because the consequent (aka the "then"  

從條件陳述中得出錯誤的推論。當一個原因是由於結果（又稱

part of a conditional statement) is true, the  antecedent (aka the "if" part) must also be true. 

條件語句的“所以”部分）為真，因此前件（又稱“如果”部分）也必須為真時，就會發生這種情況。

This reasoning is flawed because it ignores other  possible reasons for the consequent being true. 

這種推理是有缺陷的，因為它忽略了結果成立的其他可能原因。

Everyday example: Consider the statement:  

日常例子：考慮一下這句話：

"If it is raining, the ground will be wet." An  instance of affirming the consequent would be:  

“如果下雨，地面就會濕。”肯定結果的一個例子是：

"The ground is wet, therefore it must be raining."  

“地面是濕的，因此一定在下雨。”

This conclusion is fallacious because there  are other reasons the ground could be wet,  

這個結論是錯誤的，因為地面可能潮濕還有其他原因，

such as a sprinkler system or a spilled bucket  of water. The wet ground doesn't necessarily  

例如灑水系統或溢出的水桶。地面濕並不一定

mean it's raining; it's just consistent with  what would be the case if it were raining.

意味著正在下雨；而是意味著下雨的話，這與下雨時的情況是一致的。
