The subjects that were told “the goose hangs high” mean the future looks gloomy believe the standard interpretation is the future looks gloomy. So no, it is not evidence that the most subjects were being rational. In fact it shows that most people are fallible to this bias.
If we were given more information though, such as 80% of ‘looks good’ subjects think that the standard interpretation is ‘look good’, while only 60% of ‘looks gloomy’ subjects think the standard interpretation is ‘looks gloomy’, then it is an evidence that SOME subjects are rational.
