# Why “Honestly” in Tukey's Honestly Significant Difference (HSD)?

Why is the word "Honestly" in "Tukey's Honestly Significant Difference"? It seems unusual. Most statistical procedures are developed with the intent to give an "honest" answer. Why is that word used for this particular one? What's the historical background?

However, LSD fails to maintain the overall Type I error rate. The true overall $$\alpha$$ value of the multiple comparisons test is not $$\alpha$$, but is inflated to $$1-(1-\alpha)^c$$, where $$c$$ is the number of pairwise difference tested. This can lead to incorrect conclusion.
