| HP1 | Idea attention is positively related to idea survival in internal crowdsourcing | (βIdeaAttention = 0.701; p < 0.05)/Model 2 | Yes |
| HP2 | Idea appreciation mediates the relationship between idea attention and idea survival | (βIdeaAttention = 0.294; p < 0.01)/Model 1 and (βIdeaAppreciation = 1.810; p < 0.01)/Model 3 | Yes |
| HP3 | Competition for attention negatively moderates the relationship between idea attention and idea appreciation | (βIdeaAttention x CompetitionAttention = −0.004; p < 0.01)/Model 4 | Yes |
| HP4a | Ideas posted earlier in internal crowdsourcing sessions, everything else being equal, are more likely to survive | (βTimeSessionBeginning = −0.714; p < 0.05)/Model 3 | Yes |
| HP4b | The likelihood of idea survival is positively related to the elapsed time between the insertion of two consecutive ideas posted in internal crowdsourcing sessions | (βTimePreviousIdea = 0.037; p < 0.1)/Model 3 | Yes |
