Actually, I notice the very exact opposite, the worst heresies clearly tend to come from those educated folk who were groomed on how to think by whatever version of Christian school they learned from.
The Bible is there for our education. The writings of Jesus and the apostles are all we need. A humble heart and willingness to learn about the Lord are all that is required to understand.
And as far as what you said about 10 different interpretations, that happens because 1. People are false converts and have a false understanding of scripture NOT led by the spirit, 2. People blindly parrot what they've decided they want to believe that they heard elsewhere, which is a huge problem in our world today, or 3. They come from different denominations, that all say they teach the truth, all led by a pastor who learned from said denominations' Bible College, the teachings of, built upon by various historical figures, that all claim to be the truth yet say different things, showing that even historical confessions and figures are not any more accurate than anyone else.
I personally don't really care what other men tell me the Bible says, as all kinds of different men say the Bible says all kinds of different things. I trust in the Lord for me to find out the truth of it, as the Lord knows in my heart I desire to know the truth about everything in this world. Notice I never said I know the truth about everything in this world, not even remotely close. But I do desire to know what is true, and not validate what random things I decide I want to believe, like I have seen many others engage in. I can't believe people cannot critically think about the logic behind that. It blows my mind. An education doesn't equate to objective correctness. College doesn't equal IQ. Nowhere in scripture does it say to trust what other men say about the Bible, not developing your own understanding. No wonder why we live in an apostasy age. The Bible says seek your own salvation with fear and trembling. Not have another man tell you how you must become saved. You'd be messed over if you happened to trust an OSAS or romans road pastor to tell you the truth.
