How about based on the fact that you can not preferentially work one area of a muscle with a single insertion point over another.
Brb, gonna work lower biceps.
Brb, gonna hit inner chest.
It's called basic Anatomy 101. Stop listening to the bros and hit pubmed. Wait- let me guess- you also do leg raises for "lower abs." Lol.

So now we're using soreness as an indicator? You're aware that soreness is a neurological feedback not directly related to which "area" of a muscle is being worked, right?
You're also aware that- despite what Flex magazine says- muscle follows the "all or nothing" principle and either contracts fully along the length of its fibers or not at all. It doesn't do it in pieces. Look it up in any physiology textbook if you doubt me.
But just for shits and giggles let's look at it logically. Can we all agree that both heads of the pectoralis major have a distal point of attachment on the bicipital groove of the humerus? Since that's the case, when the humerus moves in any direction under any load, there's no way for one head of the pec major to contract and not the other. What- you think it goes slack while the other contracts more? With a common innervation on top of that? Really? Just...no.
Well my friend what works for some may not work for others I guess but they most certainly work for me and do INDEED work a different part of the pec you can FEEL it when training as opposed to flat.
You're absolutely right, Littleguy.
And soreness is an EXCELLENT indicator of which muscle you worked.
EKnight's studies are almost 20 years old, and they used six guys. A sample size that small is meaningless. I think the tens of millions of guys around the world who built their upper chest with incline benches and grew their pectoralis majors with flat benches since those flawed studies are a better indicator as to what is accurate. EK, can we see a pic of your pecs based on your training ideas? Here are mine based on my training ideas:
