The reporting and interpreting of archaeological investigations lags behind the actual discoveries, and archaeologists are usually trying to find what they want to find, overlooking or ignoring what they do not wish to find.

Only by perhaps a couple of years at most. Annual conferences and peer review as well as the internet have GREATLY lessened the time. Also, the current (and has been for SEVERAL decades) method is to catalog and record ALL information, in ALL strata, even if it does not pertain to the current excavation topic or period. This is done specifically so that other scholars have access to the findings. IOW, your statement “overlooking or ignoring what they do not wish to find” is not only blatantly false, but has not been the case since at least the 1930’s and casts aspersions on the ENTIRE discipline.
And you should be expecting a DIFFERENT Modus operandi?
After the ASPERSIONs that MORMONism cast on ALL of CHRISTIANITY???
