Science as a Human Endeavour: How Biological Knowledge Is Built and Used
What you must understand
This domain examines biology as a human activity. You need to understand that scientific knowledge develops through peer review, replication and the accumulation of evidence, and that it is provisional - open to revision when new evidence appears. You should know how models and theories are used and revised, how collaboration and communication shape progress, and how social, ethical, economic and political factors influence which research is funded and how findings are applied. In WACE contexts, this often involves Australian and global case studies such as vaccine development, conservation policy, genetic testing and biosecurity.
Traps that appear in questions
- "Proves" versus "supports". Scientific evidence supports or refutes hypotheses; it rarely proves them absolutely, and questions penalise the word "prove".
- Chronology of acceptance. A new idea is not accepted because it is new or because an authority endorses it; it is accepted when independent evidence accumulates.
- Confusing ethical with legal. Something may be legal yet ethically contested, or ethically acceptable yet currently restricted by regulation.
- Attributing outcomes to one cause. Social and economic factors interact; a single-issue answer loses marks.
- Ignoring the role of communication. Peer review, publication, public reporting and data sharing are all part of the process.
Rule of thumb
When asked to evaluate the influence of science on society, use a three-step structure: state the scientific finding, state the application or decision it enabled, then state a benefit and a limitation or ethical concern, each tied to a specific example. For instance, genetic screening for a heritable condition allows informed family planning, but raises concerns about insurance discrimination and privacy, which is why regulation accompanies the technology.
