• Problems are wicked
• Parameters are characterised by uncertainty
• All models are wrong
• Quants and quals

While fuel prices and low incomes are constituent factors, the real cause of fuel poverty is the energy inefficiency of the home .

....I find myself referring to reports published by CSE going back several years which presented findings that are extremely pertinent to the debates we are having now.
So one, some or all of the following must apply:
CSE is failing to communicate the things we’ve discovered;
‘the system’ (DECC, Ofgem, BIS, DoH and their former incarnations) isn’t listening to us;
‘the system’ is unable to assimilate evidence and analysis

Conclusion
•Bayesian Networks can propagate probabilistic causal relations and facilitate prognostic and diagnostic inference.
•Can combine expert opinion (subjective probability) with quantitative (frequentist probability) from multiple knowledge domains.
•Explicate a complex problem with intuitive causal map and systems thinking
•Facilitate decision making under uncertainty
But...
•Require rich data and conditional probabilities . . . we need to share data!
