Do people actually take papers in "management science" seriously?
Yes, that's the problem, many do, and they swear by these oversimplified ideas and one-liners that litter the field of popular management books, fully believing it's all "scientific" and they'll laugh at you for questioning it. It's nuts.
They do and there is nothing wrong with that. The papers published in this journal are peer-reviewed and go through multiple rounds of review. Also, note that Andrew King could carry out the replication because the data is publicly available.
