The Uncertainty Principle04:08

The Uncertainty Principle

32.7K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Uncertainty in Measurement: Significant Figures

All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Uncertainty: Overview

1.7K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

Uncertainty in Measurement: Accuracy and Precision

102.9K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Uncertainty: Confidence Intervals

11.7K
The confidence interval is the range of values around the mean that contains the true mean. It is expressed as a probability percentage. The interpretation of a 95% confidence interval, for instance, is that the statistician is 95% confident that the true mean falls within the interval. The upper and lower limits of this range are known as confidence limits. The confidence limits for the true mean are estimated from the sample's mean, the standard deviation, and the statistical factor...

Area of Science:

  • Psychology
  • Behavioral Economics
  • Decision Science

Background:

  • Uncertainty is a key aspect of life, comprising risk (known probabilities) and ambiguity (unknown probabilities).
  • While risk and ambiguity influence non-social decisions, their impact on prosocial behavior is understudied.
  • Prosocial behaviors, such as cooperation and trust, often involve navigating uncertain social outcomes.

Purpose of the Study:

  • To investigate the distinct roles of risk and ambiguity attitudes in predicting prosocial behavior.
  • To determine if individuals' tolerance for ambiguity influences their willingness to engage in costly social actions.
  • To explore the conditions under which the relationship between ambiguity tolerance and prosociality holds.

Main Methods:

  • Three experiments were conducted involving decisions related to cooperation and trust.
  • Participants' attitudes towards risk and ambiguity were assessed.
  • Behavioral choices in social decision-making tasks were analyzed in relation to ambiguity tolerance.

Main Results:

  • Ambiguity tolerance, but not risk tolerance, significantly predicted prosocial behavior.
  • Higher ambiguity tolerance correlated with increased engagement in costly cooperative and trust-based actions.
  • The link between ambiguity tolerance and prosocial choice disappeared when uncertainty was resolved.

Conclusions:

  • Attitudes toward ambiguity are a strong predictor of engaging in costly prosocial behaviors.
  • This finding suggests a psychological mechanism underlying prosocial motivations, specifically related to navigating uncertainty.
  • Understanding ambiguity tolerance offers insights into the drivers of cooperation and trust in social contexts.
