Analysis paralysis (or paralysis by analysis) describes an individual or group process where overanalyzing or overthinking a situation can cause forward motion or decision-making to become "paralyzed", meaning that no solution or course of action is decided upon within a natural time frame. A situation may be deemed too complicated and a decision is never made, or made much too late, due to anxiety that a potentially larger problem may arise. A person may desire a perfect solution, but may fear making a decision that could result in error, while on the way to a better solution. Equally, a person may hold that a superior solution is a short step away, and stall in its endless pursuit, with no concept of diminishing returns. On the opposite end of the time spectrum is the phrase extinct by instinct, which is making a fatal decision based on hasty judgment or a gut reaction.
Analysis paralysis is when the fear of either making an error or forgoing a superior solution outweighs the realistic expectation or potential value of success in a decision made in a timely manner. This imbalance results in suppressed decision-making in an unconscious effort to preserve existing options. An overload of options can overwhelm the situation and cause this "paralysis", rendering one unable to come to a conclusion. It can become a larger problem in critical situations where a decision needs to be reached, but a person is not able to provide a response fast enough, potentially causing a bigger issue than they would have had, had they made a decision.
