It was once thought that there was another Byzantine writer of the same name, Michael Psellos the Elder (now also called Pseudo-Psellos), who lived on the island of Andros in the 9th century, and who was a pupil of Photius and teacher of emperor Leo VI the Wise. Michael Psellos himself was also called "the younger" by some authors. This belief was based on an entry in a medieval chronicle, the Σύνοψις Κεδρηνοῦ-Σκυλίτση, which mentions the name in that context. It is now believed that the inclusion of the name Psellos in this chronicle was the mistake of an ignorant copyist at a later time, and that no "Michael Psellos the elder" ever existed.
The term Pseudo-Psellos is also used in modern scholarship to describe the authorship of several later works that are believed to have been falsely ascribed to Psellos in Byzantine times.
