Thanks Michael, indeed it would be a nice article. I believe that in the early stages of ideation the percentages are considerably higher. The founders of javelin board mention 98% of startup ideas fail. My concern is only at the experiment or interview level. If you ask 100 people, how many should be enough to proceed spending time/money on further analysis? Do you think 70% of positive feedback is pretending too much??
