Aside from the fact that a lot of our reality isn’t measurable (love, beauty, joy, etc.), science doesn’t yet have all the answers. It is a continually developing field. Sometimes it gets things wrong, or only partly right. Sometimes it can’t explain what is blatantly there; for instance, prior to the discovery of gravity, if you fell out of a window you’d still go “splat” at the bottom.
“Gaslighting is a form of mental abuse in which false information is presented with the intent of making a victim doubt his or her own memory, perception and sanity. Instances may range simply from the denial by an abuser that previous abusive incidents ever occurred, up to the staging of bizarre events by the abuser with the intention of disorienting the victim.” http://en.wikipedia.org/wiki/Gaslighting
“Groupthink is a psychological phenomenon that occurs within a group of people, in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Group members try to minimize conflict and reach a consensus decision without critical evaluation of alternative viewpoints, by actively suppressing dissenting viewpoints, and by isolating themselves from outside influences.”
“A straw man, also known in the UK as an Aunt Sally, is (…) an informal fallacy based on the misrepresentation of an opponent's argument. To be successful, a straw man argument requires that the audience be ignorant or uninformed of the original argument.
The so-called typical "attacking a straw man" implies an adversarial, polemic, or combative debate, and creates the illusion of having completely refuted or defeated an opponent's proposition by covertly replacing it with a different proposition (i.e., "stand up a straw man") and then to refute or defeat that false argument ("knock down a straw man") instead of the original proposition.”
