They want to create the illusion of scholarship. Remember the CREATOR book? That was aimed at intelligent people. They want to "prepare" the flock to discuss difficult concepts at the door and to run intereference with what the kids will learn in school.
Most people that ascribe to evolution believe that those that believe in creation don't know the facts. WT wants to create the image that not only do JW's know the facts, they carefully studied them and judged them, in their infinite wisdom, to be false. By bringing up this theory now, when students bump into in in school their opinions will already be formed. This gives the R&F a feeling that they have been well-educated, but actually they were simply spoon-fed a few facts and a lot of opionion. Kind of like FOX news. Now they are convinced they know the truth about the Endo-symbiotic theory so their armor is intact, so to speak. They've been innoculated against reason. Fed just a tiny bit to make them immune to the fuller picture.
It's a sort of artificial intelligence. It's lazy. The R&F will not likely study this theory independent of the WT, but they have the sense the org did the work for them and prepared them for intelligent discussion. It's a big deal to make a person feel educated. The false confidence emboldens them to disagree with things they don't understand.
Now they can continue to believe in the image they have created, "See, I'm not ignorant. I know all about this scientific theory and in my infinite intelligence and wisdom I have judged it to be false. Now let me show you why."
I used to thiink that the org prepared me SO WELL for the ministry. They fed me these pseudo-intelligent bits and I was confident I could carry on deep scientific discussions at the door. Nothing the householder said would have an impact on me, because my opinion was already formed on shaky foundation, and the actual facts or bigger picture was not going to complicate that. They could fling facts at me like bullets from a machine gun, but they simply bounced off my armor made of "I've already considered this theory and deemed it to be false or inadequate". Only I hadn't. I had only been trained by WT to think so. The false sense of knowledge they gave me made it unnecessary to actually research and think critically.
I I tell a child that glass does not break when it's dropped, and I even demonstrate it by dropping a thick glass on its heavy base, then I have intoduced some doubt. If the child thinks critically and points to the millions of times that glass has broken when dropped, I can explain that it wasn't the impact that broke the glass, it was a flaw in the glass itself. When it was manufactured there was some microscopic imperfection that compromised the integrity of the glass. As a matter of fact, impact makes glass stronger because it causes the molecule to adhere even more tightly together, and I drop the heavy glass on its base again to prove it, then the child is innoculated against the truth.
When he goes out and tells his friends that dropping glass does not break it, his friends will look at him sideways. They will argue and reason. They will drop 20 glasses and prove their point. But he will simply dismiss the evidence because he knows the real reason the glass is breaking is because it has a flaw. He will feel superior in his knowledge. He knows about microscopic things and his friends have jumped to an amateur conclusion. Of course his friends will think he's whacked, but he will simply interpret their attitude as a lack of understanding.
I don't know if that made sense. WT is busy building an armor of misinterpreted facts and false intellectual confidence. In this way they protect the R&F from the truth.
