Neurological safety and security in the Evangelion Project - a lack of defence in depth

The primary security boundary in the interface between the pilot and the Evangelion consists of the filter circuits integrated into the Entry Plug. Early designs of this interface featured additional filter circuits in the A10 neural connectors worn by the pilots. Once the Entry Plug's filter circuits were proven to be more than adequate for all reasonable situations, the filters in the A10 connectors were removed on the grounds that they impaired the pilot's synchronization ratio.

In this paper, the authors report on the psychological and physiological consequences of this design decision for two pilots who underwent emergency dual synchronization during the Angel attack on the UN Pacific Fleet.
