Default Discourse about left-right-handedness

This is not a thread where I am asking if Jack the Ripper was left handed or right handed.

It is a thread where I am asking why the doctors thought he was left handed or right handed.

Why did they interpret the wounds and marks on the victims as having been done by a left hand, by a left handed killer, by a right hand or by a right handed killer?

What can explain the variations in the discourse?

In what instances is a left handed / right handed cut /killer described?

Are the descriptions of the two types conflicting or not?

There is evidence that Jack the Ripper was left handed. There is evidence that Jack the Ripper was right handed. Why?

Pierre

1)They were killed by different people.
2)The killer was ambidextrous.
3)Position of victim/killer when slashed. Standing/on ground.

Well, could you think of some more reasons?

Pierre, the idea of which hand is based on natural drift of a straight line and better position to perform the manipulations. The evidence though was pure opinion of the doctors performing the autopsy examination. If the victim was on the floor at the time the throat was cut (as the inquests seem to suggest) and the throat cut started on the victim's left (as again) then a right handed knifeman would be more likely

Best wishes

Pierre,

Further to your ambidextrous question, the stand out is MJK. The first four canonical had a suggested throat cut from the left (Annie and Polly two left sided cuts, Liz and Catherine a lift off from left to right). MJK though was cut from the right. If there was only one knifeman in 1888 slashing throats, then there would be a high likelihood of some left handedness.

Best wishes

Paul

How does a pathologist with an interest in gut flora who lectured with his left hand secured in his clothing sound?
The is no MJK.
Her name was Mary Ann Kelly and a member of Jack's church as a youngster.

I don't think MJK is a stand out, really, more of a stand the other side.
For the first four canonicals the killer was thought to have stood (or crouched/knelt) on the victims' right when cutting the throat (for two that was probably the only place). In Kelly's case, the killer had to stand on her left side, hence the cut apparently going the other way.

Why would the killer have had to stand on her left side? Was there a law for it?

And was he actually thought to have stood on the right side, are there sources for this?

Hi Joshua

I talk with ambidextrous tendencies and some surgical training. MJK was cut from the right carotid round, if one imagines the head and hence jaw position it is not easy to cut with the right hand in that fashion. The left hand however is easy. The enforced awkwardness might explain the increased violence but my personal opinion is that the killer cut MJKs throat with his (or her) left hand, simply due to physical mechanics.

Best wishes

Paul

Hi again,

and that is the same questions: was the killer left/right-handed or "ambidextrous", and then the "likelihood of some left handedness".

So how could we analyze the discourse instead? We can try these questions:

Why did they interpret the wounds and marks on the victims as having been done by a left hand, by a left handed killer, by a right hand or by a right handed killer?

What can explain the variations in the discourse?

In what instances is a left handed / right handed cut /killer described?

Are the descriptions of the two types conflicting or not?

There is evidence that Jack the Ripper was left handed. There is evidence that Jack the Ripper was right handed. Why?

So what could be our suggested answer(s)?

Regards, Pierre
