Don't you think it would be more interesting / realistic that research do not depend on "race", allowing everyone to research everything ? I would suggest that race would allow to have access to some part of the technology tree faster, but not exclusively (like if race is psychic, then cost for psy tech is halved, but other can still try to research the area)
