| Trading |
DCE and BWS |
| • Evidence participants were comparing between alternative profiles and trading between the attribute/levels across alternatives was strongly exhibited for the DCE task. |
|
| • Evidence for trading between attribute/levels within a profile was weakly exhibited for the BWS task. |
|
| Psychological decision model |
BWS |
| • Limited but inconsistent evidence was observed supporting a sequential decision-making model. |
|
| • No evidence was observed supporting a maxdiff decision model. |
|
| Difficulty conceptualizing ‘least’ important |
BWS |
| • Some participants found it challenging to choose a least important attribute/level, when even the least important might still be perceived as either still important, or conversely as not important at all, for a funding decision. |
|
| Desire to rate |
BWS |
| • Some participants wanted to rate or rank attribute/levels to provide a more complete preference ordering. |
|
| Lack of variation |
BWS |
| • Some participants showed a lack of variation in their choices, consistently choosing the same attribute/level as least important for all profiles. |
