Fact or value

Relevant topic(s): 1.1 Introduction and When Is Science Relevant

In an international forum on climate change, the following statements are made by various parties across the globe. Identify if each of these statements is a claim of fact or a claim of value.

1. Leader of a major first world country: “The current change in global climate is not caused by humans.” (Fact/Value)
   1. A climate activist: “A world whose economy is built around environmental consciousness rather than corporate greed is a world that’s worth living in.” (Fact/Value)
2. An economist: “By my conservative estimate, the clean energy sector will create 1 million jobs within the next two years.” (Fact/Value)
3. An industry lobbyist: “More than half the population would prioritise maintaining job security over reducing the risks of climate change.” (Fact/Value)

Genetic engineering conference

Relevant topic(s): 1.2 Shared Reality

At a conference on genetic engineering, two panelists, Dr. Hallstein and Dr. Yamazawa, are having a heated debate over the effectiveness of gene editing of mosquitos in reducing the spread of malaria. Dr. Hallstein thinks the approach can drastically reduce disease spread, whereas Dr. Yamazawa argues that it has negligible effect. How can the attendees of the conference decide who is correct in reality? Choose one.

1. They cannot. Both panelists are correct to themselves, and they should agree to disagree.
2. The attendees should take a vote. The claim receiving more than 50% of the votes is the correct one.
3. They should defer to the most reputable senior scientist at the conference.
4. They cannot yet, but they can continue to gather more evidence to see which opinion is more likely to be correct.

High-speed rail

Relevant topic(s): 12.2 Denver Bullet Study

Suppose you are a government official tasked with developing a plan for a new high-speed railway system across your country. Several foreign countries, including China, France, Germany, and Japan, have already offered development plans using their own high-speed rail technology under significant foreign investment. You have also thought about developing the system entirely domestically to boost the national economy, but this will certainly take longer than foreign development plans.

You remember Prof. Campbell’s lecture on the Denver bullet study from your days at Berkeley and hope to use it to make a decision by integrating facts and values.

1. Name two factors or features of the high-speed rail plans that will play a significant role in the decision making process.
2. Name two stakeholders and two types of experts for this situation.
3. Briefly explain how the Denver bullet study technique produces or outputs a final decision on the optimal high-speed railway plan.{{Stakeholders evaluate the relative importance of items in part (1), and experts independently evaluate how well each rail construction plan achieves each of the factors/features. The stakeholders' scores are multiplied with the corresponding experts' scores, and then summed up. (Final score is the average of the experts' scores, weighted by the stakeholders' scores.}}
