If Lewis thought there were also materialists with superb reasoning abilities who believed in materialism by correctly exercising those reasoning abilities, I wouldn’t think a passage about poorly reasoned materialists was meant to be a generalization.
Why do you think he didn’t think this? I’m having a hard time not seeing this exchange as you projecting negativity onto Lewis, when he was writing about fully general cognitive biases and weaknesses with compassion towards all humans who share those biases.
If he thought that materialists became materialists by reasoning correctly, he would either have been a materialist, or would have taken one of a particularly narrow set of positions (such as “materialism is based on correct reasoning, and how something can be false and correctly reasoned at the same time is one of God’s mysteries” or “materialists are only materialists because they start with different premises from me, but correctly reason from those premises”) which as far as I know he didn’t. (Or else taken no opinion on materialism, which he wasn’t going to do.)
