The Scientific Method is applied to increase knowledge of an observation. There is no final word. There is only the aim to increase knowledge each iteration.
Is Newton’s 2nd Law, F = ma or F = m * dv/dt factual science, when F = d(mv)/dt is much more precise for all matter?
BTW, Arthur Jones is not the final say of factual science
A Dumbbell Lateral Raise has the highest level of tension in the fully contracted position, which is a conventional exercise
that is why the seated variation of it is incredibly effective
he makes a hell of alot more sense than contradictory studies
Probably the people who authored the meta analysis. And their peers who reviewed it. And the people at Renaissance Periodization who funded the study (whose training methods do not require partial ROM).
If you want to critique the methods, results, or conclusions - or have specific concerns about how the study was conducted, you should list them. Specifically.
(probably after reading the study) 
That argument MAY make sense from a strength standpoint, but not for hypertrophy. And I did not say anything about ONLY training muscles at their weakest point — don’t put words in my mouth, to strengthen your argument…
So much for keeping it civil. And the true colors of Basement Pizza Roll Armchair Training Expert come out… 
You are highly skilled at making statements that make no fucking sense whatsoever.
the seated lateral raise.
Learn to read between the lines it is not my responsibility to make it easy for you it is your responsibility to level up your understanding skills.
If you give it any thought at all, everyone wants the strengthen the muscle over its full range of motion.
The dumbbell lateral raise miserably fails at this. Zero resistance at the bottom of the movement and it isn’t close to the stretched position of the deltoids.
Try a knelling lateral raise between a cable crossover machine, grabbing the opposing handles from the bottom. Now that has a stretched resistance. I stumbled onto this use in 1976, and made a noticeable improvement in the roundness of my deltoids.
your muscle are weaker at different points of the movement so resistance being even on a cable and you lying down on a incline bench still doesn’t solve the issue
the weight has to adjust for the strength curve. this is where the plate loaded leg extensions shine best
No need for kneeling these days, with the adjustable height pulleys. Setting the pulley height at standing hand level, assures maximum resistance in the stretched position.
