Is Science Reliable

The video discusses the replication crisis in scientific research, highlighting issues in cancer and psychology studies where results could not be reproduced. It explores causes such as unreliable research tools, poor study design, and publication bias. The video also addresses the challenges in psychology experiments and the impact of data analysis errors. Solutions like emphasizing effect size and data sharing are proposed to improve research reliability.

• 47%

• 12%

• 88%

• 53%

What is a common issue with antibodies used in biomedical research?

• They degrade quickly.

• They are not available in sufficient quantities.

• They often bind to the wrong proteins.

• They are too expensive.

Why is it challenging to replicate psychological studies?

• Psychological studies require rare equipment.

• There is a lack of interest in psychology.

• Human experience introduces subjectivity.

• Psychological studies are too expensive.

What is a major reason journals prefer to publish positive results?

• Positive results are more exciting.

• Negative results are more reliable.

• Positive results are easier to understand.

• Negative results are too complex.

What is a suggested alternative to p-values for determining the significance of scientific findings?

• Sample size

• Effect size

• Control group

• Research funding

What is a p-value used for in scientific research?

• To measure the size of an effect

• To determine the probability of results being a coincidence

• To assess the ethical implications of a study

• To calculate the cost of an experiment

What is one proposed solution to improve the reliability of published research?

• Focusing on theoretical research

• Reducing the number of experiments
