Anxiety leads to a narrowing of the field of attention, the so-called tunnel vision, and when people are anxious they are unable to attend to the total situation as is necessary to enable them to act rationally, but impulsively do the first thing that comes into their heads which is usually determined by what others are doing at the same time.
Quotations by:
Brown, James A. C.
Most people want to feel that issues are simple rather than complex, want to have their prejudices confirmed, want to feel that they “belong” with the implication that others do not, and need to pinpoint an enemy to blame for their frustrations.
