Questions and Answers

What is the primary characteristic of science demonstrated by the demand for replication in the given example?

A belief in absolute certainty of results
An emphasis on skepticism and validation (correct)
An avoidance of all forms of controversy
A focus solely on minute details of experiments

When research findings are inconsistent, what does scientific practice typically encourage?

Replication of studies to assess the reliability of the findings (correct)
Accepting all initial findings without further inquiry
Ignoring contradictory results in favor of established theories
Suppressing studies that cannot be replicated

Why is it important for multiple, independent researchers to conduct replications of the same study?

To prioritize the smallest details in all experiments

Flashcards

Replication in Science

Science is a process of ongoing questioning and evaluation, where findings are rigorously tested and challenged by the scientific community. Through repeated experimentation and analysis by independent researchers, reliable conclusions can be established. This process helps to ensure the accuracy and validity of scientific knowledge.

Skeptical Attitude in Science

Scientific inquiry is characterized by a critical and questioning approach that seeks evidence to support or refute claims. Scientists are skeptical of claims and demand rigorous evidence before accepting them as true.

Focus on Details in Science

The scientific method relies on a systematic process of observation, experimentation, and analysis to uncover patterns and insights about the natural world. This process involves meticulously collecting data, analyzing results, and drawing conclusions based on factual evidence.

Uncertainty in Scientific Research

Scientific research typically involves a series of experiments designed to test a specific hypothesis. These experiments may yield varying results, highlighting the inherent uncertainty and complexity of scientific exploration.

Collaboration and Peer Review in Science

Science is a collaborative enterprise where researchers share their findings and engage in critical discussions to validate or refute claims. This process of peer review and scrutiny ensures that scientific knowledge is robust and reliable.

Study Notes

Scientific Method in Action

Skepticism and Replication: The scientific method underscores a skeptical approach to results. Initial findings, even if suggestive, are not accepted as definitive. Instead, replication (repeating the experiment by different researchers) is necessary to validate and ensure consistency of results. This ensures the reliability and validity of the study's conclusions.
Importance of Mixed Results: The presence of mixed results (some studies showing a correlation between violent media and aggression, others not) highlights the crucial need for verification. A single study doesn't automatically confirm a hypothesis; multiple studies, especially when independent, are essential to form a stronger conclusion.
Hypothesis Testing: The initial hypothesis, "Exposure to violent media content increases aggressive behavior in teenagers," serves as a starting point for scientific investigation. However, the scientific process actively explores whether observed results support or refute this hypothesis.
