You don't even have to read a scientific study. After one season of bass fishing you can learn that a 1 pounder is exponentially easier to sight fish off a bed than a 6 pounder.

I like the way you think !!

Granted, according to Jones, fish may become wary of a certain lure, but who in heck catches the same fish on the same lure any time in the future much less warns other fish from attacking it. I never use the same lure all day if not for just for the variety but the challenge of catching fish on different ones. Even my presentations are varied depending where I am on the water. If a lake had 5,000 or more fish, I'm pretty sure I can usually catch a decent percentage and not worry fish will run and hide when they hear my trolling motor from 40' away.

O'l Leroy being trained to jump through the hoop was the part that surprised me

Just thought of something that applies to lure shape. During WWII, plane spotters in the US and Great Britain were part of a citizen observation corp that volunteered to identify enemy aircraft that may endanger cities. Silhouettes of enemy aircraft were memorized just in case an alert was necessary in a night attack. It made me wonder about the various lure shapes fish are attuned to that they respond to almost reflexively. Here are what I call mini-sticks that were derived from 4" French Fries commonly used to catch bass:


I've use similar mini-grub sticks (shown in the above posts) and caught panfish, bass and catfish. These are a bit thicker but are equal in length - 2", and exhibit the same action rigged wacky style (light ball head jigs hooked in the middle) or the usual way from either end. The fact that they look like caterpillars is purely coincidental. But aside from that, their shape, size and wiggle should get fish to strike like no tomorrow. Like they say in crime shows: they fit the profile....

If a curl tail was attached to one end, I doubt the lure would work nearly as well because a curl tail alters a grub's action and profile which prompts fewer strikes if used the same ways.

On another forum, an angler made a tube lure minus the skirt using a metal spike dipped in hot plastic. I would have never thought the lure could get hit, but he's shown photos of saltwater and freshwater species that attacked it. Many other anglers on that forum really loved it, so there must be something about the basic profile and action that get fish to strike. I will make a few myself just to see if they work where I fish. Here's what it looks like:


Here's another example of a similar lure profile and action all sizes of fish and species attack:
