Learning Goals
[Link to PlayPosit]
[Link to instructional video]
After this lesson, students should
- Understand that the self-correcting and ever-changing nature of science is a strength, not a weakness.
- Feel optimistic about the capacity of science to help solve problems for societal and personal decision-making.
- Understand the assumption of shared reality with regular patterns and the power of empirical evidence as a way to study this shared reality.
- Appreciate that scientific knowledge is built more like a raft than a pyramid.
| It’s easy for students to get hung up on philosophical minutiae or edge cases of what really is reality, or does it even exist. Try to pull students back to the main goal of making practical decisions in our lives or in society by using science to understand the assumed shared reality. We only need things to be as real as the table in the middle of the room, so one can walk around it and avoid hurting oneself. |

- Raft vs. Pyramid
- The Raft
- Every scientific claim is subject to question and reevaluation; we can use the rest of our scientific knowledge to question any one claim at a time, though we cannot question the entire edifice at once.
- The Pyramid
- Science builds on fixed foundations to ever higher levels of knowledge.
- The Raft
Common Misconceptions
- Science always changes its mind. One day drinking wine is good for you, the next day it isn't anymore. Why should we trust anything scientists say?
- When scientists make any claim, they make it always with some level of uncertainty, leaving open the possibility that they may be wrong. Any claim is subject to scrutiny and may be overturned or amended by new evidence. The ever changing and improving nature of scientific knowledge is a strength, not a weakness.
Context
In this lesson, we lay the philosophical groundwork for future topics by establishing a common set of assumptions and attitudes in science, namely, that the world is full of regular patterns that can be studied empirically, and that scientific knowledge is constantly evolving in light of new evidence.
Before
- 1.1 Introduction
- Decision making relies on knowing the effects of each decision in the real world. Collective decision making thus relies on a collective understanding of the shared reality through the scientific method.
After
- 2.2 Causation and Correlation
- One important aspect of the shared reality is cause and effect, which is studied in a series of future lessons on causation.
- 3.1 Systematic and Statistical Uncertainty
- Our understanding of the shared reality is never perfect, but is always improving. When it comes to measured quantities, it is possible and necessary to quantify the inaccuracy or imprecision in our description of the shared reality.
- 5.1 Scientific Optimism
- Although the first step of a scientific attitude is to admit one's ignorance or the uncertainty in one's knowledge, it is still possible to make progress by successive iterative improvements.
- 13.2 Deliberative Polling
- A type of event that helps the public make better group decisions after being informed on the relevant (shared) facts about an issue.
