simplistic

At one time, I was extremely skeptical of such simplistic medicine until observing a reflexologist at work and finding that many of the patients showed steady improvement in cases where official medical practitioners had recommended surgery or prescribed the usual quantum of pills. Along with the foot massage, the reflexologist recommended herbal teas to her clients.

(Mao's) reliance on simplistic Soviet interpretations was reflected in his dismissal of Hitler as "a mere will-less puppet of the reactionary capitalists."
