My son (diagnosed with ASD) who recently turned 5 can be a pretty effective liar and seems to have taken to it a bit over the past few months. He doesn't use it very often to get out of hot spots, thankfully, though it does happen. He mostly seems to like to use it as a comedic device (really funny for him as it usually involves some lie deftly designed to invoke panic in me) or a way of testing/pushing people to get a reaction (oh, he likes to do that a lot -- I'll make another post about that some other time.) Now, I've heard that people on the spectrum tend not to lie or can't lie very effectively when they try. Is that really the case?
