The Scientific Consensus on When a Human's Life Begins.

Area of Science:

• Life Sciences
• Developmental Biology
• Science Communication

Background:

• Scientific literature often presents the fertilization view without citation, implying consensus.
• Public opinion is divided on whether the beginning of human life is a scientific fact or belief.
• A majority of Americans believe biologists are most qualified to define when human life begins.

Purpose of the Study:

• To survey biologists' views on when human life begins.
• To provide an expert biological perspective on the fertilization view.
• To inform science communication strategies regarding the fertilization view.

Main Methods:

• Survey distributed to biologists from 1,058 academic institutions globally.
• Respondents assessed survey items on the beginning of human life.
• Quantitative analysis of expert opinions on the fertilization view.

Main Results:

• 96% (5,337 out of 5,577) of surveyed biologists affirmed the fertilization view.
• The fertilization view was the most popular among public health and IVF professionals in prior studies.
• A significant gap exists between the scientific consensus and public understanding.

Conclusions:

• The fertilization view is the predominant biological perspective on the beginning of human life.
• Scientists have an ethical obligation to communicate scientific findings on this topic.
• Enhanced science communication can empower public understanding and informed decision-making.
