You go from “Kahneman (1982) suggests that X”, to “Kahneman has shown that X”, to “It is well established that X”, to “Since X”, and finally you don’t even mention X any longer, it has merged into background knowledge.
Unfortunately, this process can occur even in the absence of any attempt to obtain evidence for X. Sometimes just by accident.
