Reliable decision making
Poor decision making is a major factor causing climate change (and many other global problems).
To tackle climate change, decision making needs to be improved.
A key part of this is to recognise that
- good decision making is difficult
- determined efforts are needed to avoid errors.
Fallacies and cognitive biases currently dominate opinions and public policy making
It is easy for people to be misled and then become convinced that they are right.

It is very hard to believe, but the squares marked A and B are actually the same shade of grey!
Things that appear to be obvious are not necessarily true.

Things that appear to be obvious are not necessarily true.
The current process of making public policy (such as how to stop climate change) is failing.
Current methods give different answers to the same question e.g. how much investment should be put into cycling. Which policy is correct is hardly ever discussed by those in positions of power.
Scientific methods have evolved to overcome biases and give correct answers to complex questions
The essence of scientific methods is that they give correct answers to questions that we feel have correct answers. We are confident that they work because (a) they give consistent answers, and (b) they make accurate predictions.Some key points of scientific methods are
- absolute honesty and zero tolerance of dishonesty
- treating each other with respect
- giving sources for all contentious statements so that the statements can be checked, and the evidence base is shared
- working together to resolve uncertainties and disagreements
- being open to scrutiny and challenge, and answering any challenge to the satisfaction of any reasonable challenger
- developing a robust evidence based consensus
Scientific methods are needed in policy making in climate change and other major problems
The use is currently common within the medical and associated professions, but needs to be extended.Nicholas Maxwell (philosopher of science) has argued that humanity needs to "learn how to resolve its conflicts and problems of living in more just, cooperatively rational ways than at present" [1].
It seems clear that applying scientific methods to decision making more extensively would improve them enormously.
Decision making should be science-based, not just evidence-based
There has been a move to advocate "evidence-based decision making", but poorly trained or unscrupulous politicians can just select a piece of evidence that fits with what they have decided to do, and claim that their decision is evidence-based.All policy making should be science-based
If the process is fixed, the correct decisions will be made.The immediate goal should be to make campaigning science-based
There is a need for- consistent and accurate policy decisions
- campaigners to set the standard that those in positions of power should follow
- a minimum quality standard on policy making to be agreed
- identify and challenge fallacies
- avoiding inadvertent repetition of fallacies
Progress towards making climate policies science-based
Organisations taking a science-based approach are- the youth climate activists
- Scientist for Global Responsibility and their Science Oath for the Climate [2]
- Extinction Rebellion
