Here is another way to describe the quadras
note: conservative and liberal in this thread is not used in a political context. Liberal here means not attached to an established belief, ready to take risks.
Alpha: liberal value savers, not good with conservative value production. (Makes a new vaccine, but they have a disregard for how effective it will be on the market, or if there will even be a market)
Beta: liberal value producers, not good with conservative value saving. (Markets this new vaccine. They just have to make sure they do it competently!)
Gamma: conservative value producers, not good with liberal value saving. (Leads the production of the vaccine, but they cannot distinguish whether or not there is something wrong with it)
Delta: conservative value savers, not good with liberal value production.
Edited for political correctness!
(Menial workers. It is difficult for them to come up with an idea and market it on their own)
