I already do this if I'm doing any serious research, but part of learning is exploratory. Needing to suspect that EVERY sentence could be a lie kills the momentum.
I'm not a professional scientist. I'm just an enthusiastic amateur. I have a full time job and don't have the time to do all that all of the time.
I should be able to read a damn blog about ants without being worried a machine is feeding me lies from a ghost.
