Define replication crisis
Highly noted studies in psychology are not replicable (raises the issue of methodology)
Where else has the rep crisis been observed? and how has it been found (2)
Physics: Cold nuclear fusion
Medicine: only 4% of Genetic literature has been replicated
Ozone layer detection: Thought the instruments were faulty when examining the Antarctic ozone layer hole
Types of replication
Exact replication: Testing the study using exactly the same methods
Conceptual replication: Testing the theory of the study using different population, variables etc
What did the Open Science Forum Collaboration (2015) find
only 36% of journals and articles have been replicated
Social psychology is the worst - 23%
Cognitive articles were the best (still bad) - 48%
What area is under scrutiny particulary?
Behaviourist social psych
Using priming or cues to induce a subconcious response (e.g., priming intelligence to see if intelligence can be created)
E.g. primed professor or football hooligan - found professors did better on tests. This has not replicated (Shanks et al., 2013)
Why might the replication crisis have occured? (5)
(Sheilds, 2000)
Solutions to rep crisis (and example)
What is p hacking?
Dredging data to find an effect, when one may not actually exist
What is publication bias? 3 facts about it
Tendency to publish only significant findings
What other kinds of bias?
Reference bias: where researchers cite only significant literature to bolster the validity of their claims
Why is the publication so bad!?
What is okay to be excluded?
Studies with poor methodology, insufficient power, poor construct validity
Cleophas (1999) (2)
World Health Organization
1/10 people suffer from some form of mental illness worldwide
Why do researchers shy away from using mental health service users?
What is a gatekeeper and what are their responsibilities?
Research that highlights need to revise mental health services?
Rosenhan (1973)
Theory behind research that is still applicable today?
Labelling and differential treatment (echoes Money & Erhhart, 1979).
Such that once a person is labelled one thing, all of their behaviour is attributed to be because of that label. Mental health service uses may face stigma and exclusion from research because of this label, but their contribution may barely differ, if all, from the contributio of ‘normal’ patients.
When is it important to check participants mental health though?
Why important to use mental health service users?
To improve the system and treatment, their voices must be heard.
Case study examples of exploitation (2)
Klein et al (2014)
Used 6000 participants, a more ‘deep and narrow’ approach.
The studies had to be simple to administer and done online.
The studies were examining effects - and 77% were replicated
Camerer (2018)
investigated articles published in Science and Nature, 21 systematically chosen studies using 5x larger sample sizes.
62% were replicated
