The Evidence for Evolution02:55

The Evidence for Evolution

47.7K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Nature and Nurture01:10

Nature and Nurture

22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Confirmation Biases01:31

Confirmation Biases

8.1K
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?

Stereotype Threat and Self-fulfilling Prophecies

41.9K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Routes of Persuasion02:20

Routes of Persuasion

68.5K
Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

What is Evolutionary History?02:35

What is Evolutionary History?

43.0K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Summary
This summary is machine-generated.

Public health evaluations of e-cigarettes from NASEM and PHE reached different conclusions due to differing priorities. Understanding these differing values is crucial for effective e-cigarette policy and harm reduction strategies.

Area of Science:

  • Public Health
  • Tobacco Control
  • Risk Assessment

Background:

  • Two major 2018 evaluations of e-cigarettes by NASEM and PHE yielded divergent public health policy recommendations.
  • Despite apparent consistency, differing core challenges and evidence criteria shaped the conclusions of each report.

Purpose of the Study:

  • To analyze why two major e-cigarette evaluations reached different public health policy conclusions.
  • To explore how differing priorities and framing influenced the interpretation of evidence regarding e-cigarettes.

Main Methods:

  • Comparative analysis of the National Academies of Science, Engineering, and Medicine (NASEM) and Public Health England (PHE) e-cigarette evaluations.
  • Examination of the central questions and evidence standards prioritized by each report.

Main Results:

  • NASEM prioritized protecting nonsmokers and preventing renormalization, demanding causality-focused evidence.
  • PHE focused on reducing current smoker morbidity/mortality, prioritizing "relevant and meaningful" evidence on immediate harms.
  • Competing priorities determined the evidence considered conclusive for impacts on smokers, bystanders, and youth.

Conclusions:

  • Differing public health priorities (protecting nonsmokers vs. aiding current smokers) led to contrasting conclusions on e-cigarette policy.
  • Understanding how values and framing shape evidence interpretation is essential, especially with new data on e-cigarettes as cessation tools.
