The authors addressed the genetics issue. You are free to disagree with them of course, but without any contrary evidence GQ is not the place to do so. At this stage the fact is that evidence can be discounted. If you want to debate the authors’ conclusions that genetics is not an issue on the study issue then we can take it up in GD.
The authors also addressed the diet issue, by pointing out that it varies as much or more over century timescales within regions than it does between regions at the same time.
In both these cases your criticism is reasonable, but neither has any evidence to actually support it. And in both cases if they were true all they would do is serve to make it impossible to judge medieval heights any more accurately than this study has done. IOW if your criticisms are valid then this study is the best analysis we will ever achieve of the height of medieval men but it is of dubious trustworthiness. And if they are incorrect then this study is the best analysis we will ever achieve of the height of medieval men and totally trustworthy.
But either way this is the best evidence we have, the only facts we have and either way the conclusion is the same: men from this time period were not substantially shorter than modern men from the UK or US and knights and other nobility were likely the exact same height.
While I understand your point here you still have yet to produce any evidence for your claims that medieval Europeans from England, France and Germany were significantly shorter than they are today. IOW at this stage we have evidence that they were no shorter that you think is flawed (reasonably enough), but no evidence at all that they were shorter.
I have seen plenty of other evidence which all reaches the same conclusion: that while medieval knights were slightly shorter than modern men it wasn’t spectacular. Until you can produce some evidence to the contrary that is what the facts say. Your experience looking at armour in museums does not go any way at all to supporting your position.
Firstly Japan is not even remotely like the climate of Northern Europe. Northern Europe ranges form frigid to cool temperate, Japan ranges from warm temperate to wet tropical. Japan is distinctly monsoonal while Northern Europe ranges from distinctly Mediterranean to mild continental.
All you have to do is look at the average temperature for Kyoto compared to Brest, which is the closest “Northern “European city I can think of
Secondly nobody is proposing that you take it as the height of Japanese people at the same time. I am proposing that you take the heights for Northern Europeans at the time, that the authors say they have treated so as to be representative of Northern Europeans of the time, and use it as a representation of Northern Europeans at the time.
How else would you describe a full grown man that is the same size as a typical twelve year old boy? That is what people have been saying in this thread
You yourself have said that they had a height some 5 inches shorter than modern men because that’s what the armour looked like. While not quite a dwarf that is substantially shorter than today, and is not supported by the evidence which says the height difference was at most two inches and that their probably wasn’t any height difference at all
But the height difference according to that study was only 1/10th of an inch. So where did this three inches stuff come from.
Look, at this stage the best evidence we have says that the height difference between medieval knights and modern men is in the magnitude of an inch at most, and very likely there was no difference at all.
And we have explained why you simply can not use suits of armour as guides to height.
So do you have any actual evidence for this three inch height difference that you are purporting to exist? And I note that this height difference went from the original ~12” difference down to your original ~5” difference to your current 3 inch difference. If this trend continues it will become a 1” difference that I am happy to accept and we can leave it at that.
