If a person decision is affected by barriers, then he will not make a sound decision. He will use
historical facts and known facts only and will not investigate further to make good decision. For instance, blacks are always considered uneducated and thus not given high positions. Likewise, it is believed that women will leave job once they married so they will not be offered good career path unlike their male colleagues.
How does barrier to critical thinking stop us from making good decision judgments?
