THAT IS NOT THE DIFFERENCE BETWEEN DEDUCTION AND INDUCTION! Deduction is the form of logic that causes the conclusion to be certain: "Socrates is a man, all men are mortal, therefore Socrates is mortal". Induction is the form of logic that causes the conclusion to be uncertain: "I see Mr. Watson has cigar dust on his coat, therefore he probably has been smoking (although he might have just been in a smoky room or something)".)
Either can be used either way. You can deduce from particulars to generalities: "My two hands both have thumbs, and I only have two hands, therefore all of my hands have thumbs", and you can induce from generalities to particulars: "Most people who pronounce 'th' as 'z' are French, therefore because you do that I assume you are French".
