The truly intelligent person will see the way the other person stands to benefit. That's how you avoid getting scammed. Unless you truly believe some stranger is offering you this great opportunity out of the goodness of their heart (in which case you have a thing or two to learn about people in general).

And if I can't understand how the other person benefits? I'm immediately suspicious.

This is not really a factor. A good scam involves the scammer and the mark going in on something together. What the scammer (ostensibly) gets out of the scheme is part and parcel of the pitch.
