Post truth, reception scepticism and emission scepticism

Beliefs lead to action and are manifested in action. We act according to what we believe, and not always do our beliefs constitute knowledge. It is beliefs that lead us (given certain desires) to act, and as these may be false, our attempts are sometimes (for this reason) frustrated: our actions do not succeed. To the extent that our actions affect other people, erroneous beliefs can lead to wrongdoing, injury or damage. For all these reasons, as epistemic and moral agents, we must try to be reliable in shaping our beliefs (we have to apply what I call 'reception scepticism' here) and perhaps even more so when transmitting them (we have to apply what I call 'emission scepticism'). Even more so in this so-called post-truth era.
