You gun knife analogy misses out the action at a distance capabilites of a gun versus a knife which is clearly one of its main benefits. By ignoring that you come up with a completely flawed analysis. As well as ignoring the action at a distance problem you ignore the ability of people to run from a knife which they are not so able to do with a gun. You also ignore the likeihood of fewer casualties in subduing a knife wielder rather than a gun carrier. All in all a completely flawed analysis.There's two ways of measuring efficiency. The first is maximum output for minimum input. The second is maintaining maximum output applied to achieving the aim, while producing minimum excess or unusable output.
Combining them together we get a model for perfect efficiency:
Zero input for infinite applied output and zero excess output.
Any increase in input, or any decrease in applied output or any increase in excess output results in decreased efficiency.
In this model I am using "infinite applied output" to define the total amount of output required to achieve the aim and nothing else.
In the gun/knife model I think the input is comparably low for both:
Knife has low "setup" input (buy knife)
Gun has a moderate "setup" input (buy gun, buy ammunition, load ammunition into gun)
Knife has a moderate to high "execution" input (stab victim with knife)
Gun has a low "execution" input (pull trigger)
The applied output for each is quite variable, but fairly high:
Applied output for knife ranked by liklihood:
1. Non-fatal injury, requires additional input (low output)
2. Fatal injury, delayed death (moderate output)
3. Immediate death (high output)
Applied output for gun ranked by liklihood:
1. Fatal injury, delayed death (moderate output)
2. Immediate death (high output)
3. Non-fatal injury, requires additional input (low output)
Note that these output rankings assume no intervention by a third party (for example immediate medical treatment).
In terms of excess output I think both are quite efficient. Neither is likely to inflict significant damage outside the aim. Minor excess output would include damaging clothing but I can't think of much else.
From this I would conclude that both a gun and a knife are fairly efficient methods of killing people, however I would argue that a gun is moderately more efficient mainly because of a higher applied output.
If we look at the gun/nuclear weapon example:
-The setup input for a nuclear weapon is very, very high
-The setup input for a gun is relatively low
-The execution input for a nuclear weapon is very high (primarily because nuclear weapons are typically very large, and thus difficult to deploy regardless of method)
-The execution input for a gun is very low
-The applied output for a nuclear weapon is very, very high
-The applied output for a gun is moderate to high (varies as per above)
-The excess output for a nuclear weapon is very, very high
-The excess output for a gun is very low
I would conclude from this that a gun is substantially more efficient for killing people than a nuclear weapon.
Of course the above is for the killing of one or several individual people. If the aim is not to kill people but to destroy an entire city, this obviously changes things dramatically and I would argue that a nuclear weapon is more efficient than a gun.
In relation to nuclear weapons versus a gun given the starting conditions I tabulated the nuclear weapon is enormously more efficient. The logic of the gun lobbyists is the argument of the arms race.
