Of all the Causes which conspire to blind
Man's erring Judgment, and misguide the Mind,
What the weak Head with strongest Byass rules,
Is Pride, the never-failing Vice of Fools.
Whatever Nature has in Worth deny'd,
She gives in large Recruits of needful Pride;
For as in Bodies, thus in Souls, we find
What wants in Blood and Spirits, swell'd with Wind;
Pride, where Wit fails, steps in to our Defence,
And fills up all the mighty Void of Sense!
If once right Reason drives that Cloud away,
Truth breaks upon us with resistless Day;
Trust not your self; but your Defects to know,
Make use of ev'ry Friend--and ev'ry Foe.
A growing area of research has been to examine various psychological aspects of risk taking. Researchers typically run randomized experiments with a treatment and control group to ascertain the effect of different psychological factors that may be associated with risk taking. Thus, positive and negative feedback about past risk taking can affect future risk taking. In an experiment, people who were led to believe they are very competent at decision making saw more opportunities in a risky choice and took more risks, while those led to believe they were not very competent saw more threats and took fewer risks.
