In the other case, analogical distance was not varied directly in terms of the stimuli, but was manipulated in a "one or more stimuli vs. no stimuli" way. All stimuli were near analogies. They found a negative effect of the near stimuli compared to seeing nothing: [[EVD - Engineering students who were given one or more near analogies as stimuli generated design ideas that were perceived as less original and valuable by potential customer judges, compared to being given no stimuli - @dahlInfluenceValueAnalogical2002]]
In the one case, analogical distance was measured post-hoc from the analogies that the sample of engineering students turned out to use (think of; not given). They found a positive correlation between % far analogy use and originality/value: [[EVD - designs that were measured during an ideation session to have come from a higher percentage of far analogies were perceived as more original and valuable by potential customer judges - @dahlInfluenceValueAnalogical2002]]
