Ethics in Research01:56

Ethics in Research

23.2K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Blinding01:11

Blinding

2.5K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Naturalistic Observations

15.6K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Deindividuation00:57

Deindividuation

26.7K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

The Placebo Effect01:54

The Placebo Effect

6.3K
The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Summary
This summary is machine-generated.

False-purpose deception, a common research method, does not impact honesty in incentivized tasks. Despite participant concerns, this deception type is not fundamentally problematic but should be a last resort.

Area of Science:

  • Behavioral Economics
  • Psychology
  • Research Ethics

Background:

  • Deception in research is debated, with psychologists favoring its use for unbiased measures and economists cautioning against it due to potential participant suspicion.
  • Experimental studies on false-purpose deception, a prevalent form, are scarce due to methodological challenges like attrition and confounds.

Purpose of the Study:

  • To experimentally determine the extent to which false-purpose deception affects honesty in research participants.
  • To investigate the impact of false-purpose deception on honesty using incentivized measures, addressing a gap in experimental research.

Main Methods:

  • Conducted two pre-registered studies with over 2000 crowdsourced participants.
  • Employed coin-flip and die-roll tasks, common incentivized measures of honesty and unethical behavior.
  • Deliberately provoked suspicion of deception to test its effect on honesty, and assessed past experience with deception.

Main Results:

  • False-purpose deception did not significantly affect honesty in either the coin-flip or die-roll tasks.
  • Participant suspicion of deception and prior experience with deception did not influence their honesty.
  • Incentivized norm measures revealed participant reservations regarding the use of false-purpose deception by researchers.

Conclusions:

  • False-purpose deception does not appear to be fundamentally problematic for measuring honesty.
  • Researchers should consider false-purpose deception a method of last resort due to ethical considerations and participant reservations.
  • Further experimental research is needed to explore the causal effects of other deception types and their potential spillovers.
