Hindsight Biases01:12

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
Prediction Intervals01:03

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...
Randomized Experiments01:13

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

科学领域:

  • 心理学,政治学,行为经济学

背景情况:

  • 面部外观影响选民的看法和选举结果.
  • 以前的研究主要集中在成年选民的看法上.

研究的目的:

  • 调查儿童的面部偏好是否可以预测选举结果.
  • 为了比较儿童和成人在选举结果中的预测准确性.

主要方法:

  • 进行了两项实验,涉及儿童和成年人评分候选人的脸.
  • 成年人根据感知到的能力来评价面孔.
  • 孩子们根据他们对假设角色 (船长) 的偏好来评价面孔.

主要成果:

  • 儿童和成年人的面部偏好与实际选举结果相关.
  • 预测准确度在两个年龄组都是一致的.

结论:

  • 面部外观在不同年龄组的政治感知中发挥着作用.
  • 从面部推断特征的能力,影响投票行为,可能在生命早期发展.
