When you are learning complex principles and concepts throughout your school careers, it is very important to start with the basics. Which is why people have incomplete understandings of a lot of ideas until they are corrected by further study of the material (ie. a higher level course with the same subject matter). It's not a matter of forcing a student to take something on faith, it's a matter of them understanding the general idea of the principle before the nitty gritty, and often complex, details are divulged.
Think of this: when you are in elementary school, learning grammar and sentence structure for the first time, what do they tell you? You cannot begin a sentence with a conjunction (and, but, because, etc.). The teachers tell you it's against the rules. Why? Because try explaining the concept of complex sentences to a first grader. Try explaining what a clause is, and what qualifies a sentence as a sentence. They won't understand, because they don't know the basics. It isn't until high school, where multi-clause sentences are first taught, that using 'and', or 'but' at the beginning of a sentence is accepted.
It is the same with scientific concepts. Start with the overall concept, with the basics, and fill in the difficult details afterwards. It is a tool to make the teaching process easier on both the teachers and the students, not to make students believe in something that isn't true.
