Is there a word or phrase for the bias of not knowing what came before? Of thinking that an idea under consideration is truly new? I'm looking for a word to describe the bias that comes from this thinking, and not the act of not knowing itself (i. e. "reinvent the wheel").
For instance, I work as a web developer, and junior developers are all the time coming up with "new" ideas that have been with us for decades. In not being aware of the history, they end up wasting time recreating existing work and making old mistakes. I'm also pretty sure this happened to the field of semiotics, which was discovered twice because the work done by earlier groups was somehow not evident to later semioticians.
I was looking for "historical bias" or "ahistorical bias," but couldn't really find anything. I'm sure there must be a word! It would be used in the following way:
The ignorance of the developers was an example of __________.
