---|---|---|
1 | Effective ignorance | Knowledge of the factors that govern this effect is so weak that we are effectively ignorant. |
2 | Ambiguous sign or trend | Some effect is expected, but its sign or trend is not clear. There are plausible arguments either direction (effect could be positive, could be negative; could increase or decrease). |
3 | Expected sign or trend | It is clear what the sign and trend of the effect will be. However, there is no plausible or reliable information on how strong it will be. |
4 | Order of magnitude | It is possible to give a rough indication of the magnitude of the effect, a qualitative scoring (e.g. 1–10 scale), or a rough comparison with other effects. |
5 | Bounds | It is possible to estimate the bounds for the distribution of the effect, e.g. its 5/95 percentiles (effect is only 5 % likely to be more than … and only 5 % likely to be less than …). However, the shape of the distribution, or best-guess estimates, cannot be provided. |
6 | Full probability density function | It is possible to provide a full probability density function; the bounds as well as the shape of the distribution. |
