People often determine the importance of a trait by examining how much attractiveness is affected by altering the trait. E.g. by using morphs like these:

Shitgonion
Obtuse Gonion
Good Gonion
Acute Gonion


People conclude, from these morphs, that the gonial angle is one of—if not the—most important factors in a jaw’s attractiveness. Wrong.

Gonial angle is an overrated part of jaw aesthetics. Why? The morphs contain a major fallacy in looks theory; the fallacy is when you morph a trait and inadvertently change another trait that’s actually more important for attractiveness, but you think the trait that you intended to morph is the main cause of the resulting attractiveness differences.

In the morphs above, the intention was to compare different gonial angles, but what actually happened is the mandibular angle and ramus length were dramatically altered in the process. The latter 2 traits are much more important than gonial angle is.

The most important factor in the attractiveness of a jawline in the side profile view is the angle between the mandibular body and the Frankfurt Plane (which is the same as the horizon when the head is facing straight ahead (not tilted upwards or downwards)).

15 Degrees2


Henry Cavill’s mandibular body goes 15º under the horizon line (Frankfurt Plane). 15º is ideal.

This is the angle that really makes or breaks jawlines. Too shallow an angle and it has a Short-Face-Syndrome look. Too deep an angle and it has a downward-grown, horse-faced look.


The height of the ramus is also very important for a masculine-looking jawline.

So you see, the “gonial angle morphs” are really more like “mandibular slope and ramus height” morphs:

Shitgonion
Obtuse Gonion
Good Gonion
Acute Gonion


The mandibular slope and the ramus height—not the gonial angle—are the main reasons for particular morphs looking attractive and unattractive.

It’s impossible to change the gonial angle exclusively; geometrically, changing gonial angle must change other angles and ratios of the jaw. Despite that, there are ways to morph gonial angle while minimizing side effects. Like so:

Obtuse Ok Gonion
Good Gonion
Acute Ok Gonion


These gonial-angle morphs keep the same mandibular slope of 15º. We can see how gonial angle by itself isn’t as crucial as many looksmaxers think. The 3rd morph’s gonial angle is close to 90º, but it isn’t anything close to as comically bad as what most people think a 90º gonial angle looks like:

Acute Gonion


This comical morph not only made the gonial angle 90º but also made the mandible angle be parallel to the horizon, and the latter makes a bigger effect on his attractiveness than gonial angle itself does.

Avoid the Side Effect Fallacy.

No shit, but it’s more about the other stuff than the gonial angle itself.

Just having a bad gonial angle isn’t really that bad.

A common moment of cope is when people see a dude’s unaesthetic jaw and say, “It’s because of his shitty gonial angle bro!” His bad jaw is caused by things that’re related to the gonial angle but are also distinctly different.

Yea let me just set up frankfurt plane to measure mpa. Just extra work for nothing

In the image editing software I used to make the morphs, measuring mandible slope takes 1 click, and measuring gonial angle takes 2 clicks and a key-holddown.

A side profile with good posture shouldn’t be more than 1–2 degrees off the Frankfurt Plane anyway. It’s how a human head is naturally angled when looking straight forwards.

And measuring is largely irrelevant because you don’t have to measure someone’s angles and ratios to know why they look good/bad. If I see a downward-grown horsecuck’s side profile, I instantly tell that his jaw’s shittiness is mainly attributed to a mandibular angle that slopes too much downwards.

This downswung jaw’s gonial angle is 115.6 degrees.

Its mandibular angle is 25.6 degrees under the horizon (15 degrees is ideal).

Yes mandibular plane angle should be the measurement that determines whether a jaw has good foundation for being attractive or not.

Usually gonial angle is very hard to measure accurately. With different pictures of the same person the gonial angle could be measured for +/- 2 degrees of error even when the gonion is somewhat defined.


And also many people that get jaw surgery (bsso ccw rotation) to change the high gonial angle still can have unattractive jaws due to their mandibular plane angle still being too high.



So yes good thread.

very nice, luscious, and intense thread. a quality read and a well-deserved rep will be delivered briefly.

i've often said something similar about the nose.

in and of itself, most nose work, but noses that have a mostly straight bridge with slight upturning work because they simulate more forward grown maxilla, regardless of how well grown the maxilla usually is. since dorsal humps, hook noses, too downturned tips tend to be causatively associated but not exclusively so, with recessed / downgrown developmental patterns.

Good thread man. I also made a thread regarding Mandibular Angle and it's importance. Yeah, it's definitely much more important that Gonial Angle.

Gonial angle would have been a fine measurement, if everybody had the same ramus tilt angle. Also, I'd love to hear what you have to say regarding the following stuff:

Obtuse Ok Gonion
Good Gonion
Acute Ok Gonion


In your morphs, a less slanted ramus (+longer mandible) would be percieved as more attractive from the front too. Due to the importance of the gonion relative to the lips from front, as the widest part of your face will be just below your lips.

Imo, that would give a way less DOM front view:
1713913516980


Its interesting, because despite a more "slayer" side view, you will look less DOM front. It's a win-win tbh, because if you are in the situation where your mandible is long, despite the more "feminine" position where your gonion lies, you clearly already have sufficient masculinity.

Not sure if you changed the forward growth of all features, but I also saw that you can give a significant percieved effect of forward growth from increasing mandibular length (i.e. Jaw Angle Implants can create illusion of considerably more forward growth of the Splanchocranium).

So somebody who had Braces with Elastics to move their lower jaw forward, could severly benefit from Ramus implant?

Also, can you let me know if slanted ramus is even naturally possible without Orthotropics (and bringing the lower jaw forward to treat Class 2)?

hey i want you to have a look at my gonial angle and mandibular angle if you dont mind? i tried to view your profile to send a message but it wont let me
