The Stanford Prison Experiment03:20

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
Censoring Survival Data01:09

Censoring Survival Data

Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different reasons...
Trial and Error and Algorithm01:12

Trial and Error and Algorithm

A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light bulb,...
Enhanced Elimination of Poison01:26

Enhanced Elimination of Poison

Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...
Punishment01:27

Punishment

Negative reinforcement and punishment are often confused but serve distinct functions in behavior modification. Reinforcement, whether positive or negative, increases the likelihood of a desired behavior, while punishment decreases it.
Punishment can be positive or negative. Positive punishment involves adding an undesirable stimulus, such as scolding, to decrease a behavior. Negative punishment involves removing a desirable stimulus, such as taking away a favorite toy, to decrease behavior.
Confirmation Biases01:31

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Area of Science:

  • Forensic Science
  • Legal Studies

Background:

  • Scientific evidence is increasingly used in criminal cases.
  • Existing rules for admissibility of scientific expert evidence have developed over time.
  • Concerns exist regarding the reliability and potential dangers of scientific evidence.

Purpose of the Study:

  • To review the general reliability of scientific evidence.
  • To trace the development of rules for admitting scientific expert evidence.
  • To criticize existing rules and propose changes for protecting the accused.

Main Methods:

  • Evaluation of relevant case law.
  • Analysis of existing admissibility rules for scientific evidence.
  • Development of new tests for scientific admissibility.

Main Results:

  • Current rules for scientific evidence admissibility are criticized.
  • Proposed changes aim to enhance protection for accused individuals.
  • Judges should exercise more discretion in excluding dangerous scientific evidence.

Conclusions:

  • Trial judges must actively determine the actual reliability of scientific evidence ad-hoc.
  • New admissibility tests are proposed, considering the proponent and proximity to the ultimate issue.
  • In judge-ruled trials, judges should favor scientifically accurate theories over convincing experts.
