===Neuroscience=== In [[neuroscience]], postdiction indicates that the brain collects up information after an event before it retrospectively decides what happened at the time of the event ([[David Eagleman|Eagleman]] and Sejnowski, 2000<ref name="Eagleman_Sejnowski_2000">{{cite journal |vauthors=Eagleman DM, Sejnowski, TJ | title=Motion integration and postdiction in visual awareness | journal=Science | volume=287 | issue=5460 | pages=2036β8 | year=2000 | pmid=10720334 | doi=10.1126/science.287.5460.2036| bibcode=2000Sci...287.2036E }}<!--|doi-access=registration--></ref>).
