Scales for converting qualitative weightings into quantitative weightings for FCMs

Qualitative weighting							Quantitative weighting
Amount of evidence flow	Rate of evidence flow	Reliability of evidence flow
		Credibility and reliability	Distortion	Hackability (generativity)	Availability	Political-ness
Not at all	No flow	Very unreliable	Very distorted	Very hackable/flexible	Unavailable	Very political	0
Small amount	Slow flow	Unreliable	Distorted	Hackable/flexible	Little availability	Political	0.25
Moderate amount	Moderate flow	Neutral reliability	Neither distorted nor clear	Neither hackable/flexible nor secure/rigid	Moderate Availability	Neither political nor apolitical	0.5
Large amount	Fast flow	Reliable	Clear	Secure/rigid	Available	Apolitical	0.75
Very large amount	Very fast flow	Very reliable	Very clear	Very secure/rigid	Highly available	Very apolitical	1
