Autism and honesty
Aspies can’t tell lies. Or so that ridiculous theory goes.
Those on the Autistic Spectrum are quite capable of bending the truth, just like every other flawed human being on the planet, but perhaps the idea comes from the fact that many Aspies are so dedicated to searching and delivering truth. Or at the very least are direct enough to appear extreme in their take on honesty. This can come in many forms.
Some people are disproportionately concerned with a universal truth and spend a great deal of time involved in ‘research’ on current affairs, religion, science, politics and other heavy topics they often bore those around them with. For these Aspies, informing people of the real truth is of utmost importance and they cannot understand why others either cannot understand or refuse to believe.
