This is so funny to me because the ingredients are all listed and well-regulated.

But the supplements and essential oils that antivaxxers often love are virtually unregulated, so you literally can't know what else is in them...

carry half of a genetic mutation that would lead to CF

Jumping in here to make a small correction: you carry one copy of the gene, not half (you have two of each of your 23 chromosomes, which both carry mostly the same DNA, but they are not quite identical). It's a recessive trait, so you need to carry two copies of the gene to have the condition; one copy and you're a carrier.

Is there anything in particular that is made particularly difficult by your condition, that other people might not think about, or would be surprised by?

Suppose people get them voluntarily as part of a commercial thing, and they have bits in every part of the brain that we could conceivably want them, would a lifetime of data from many subjects be sufficient to establish a way to switch things from Daniel Kahneman's "system 2" thinking to his "system 1" thinking? (2 being slow, deliberative thought, 1 being the preferred, quick, snap decision thought). I am writing a book about this haha

Not exactly. The condition is caused by a loss-of-function mutation in the gene(s) coding for the CFTR protein, so it's not so much the mutations working together to cause an effect, but rather that they both don't work properly and so person doesn't have the "back up" copy that they usually have (said 'back ups' are the reason carriers do not exhibit the condition). I mean, technically that's 'an effect' but it would be more accurate to describe it as the loss of the effect of the CFTR protein.
