I only have stock to go on, but here's what I see from it:

In AI_Research.txt->Add_Wanted_Tech_Areas_For_Designs(), called from [race]_Main_Script.txt->Main,

it looks like this test always true:
"if (add_all) or (not item_added) then"
because add_all is always FALSE and item_added is always FALSE
