"It is a good idea to try to get your opponent on your side by making statements that you know he agrees with – this puts you in the strong position in the debate. You don’t even need to use a fact relating to your debate – you could, for example, in a debate about the existence of God state “I am sure you agree with me when I say that petrol is overpriced”. As soon as your opponent agrees, you have won a psychological battle. You are no longer the opponent – you are a comrade. This technique is so effective it is used by telemarketers all the time."
Hey Rug, petrol's gotten pretty expensive recently.
