So a risk of 200k ISK is greater than a risk of 2bn ISK according to this “sensible definition”? Yeah, no. That's why that particular definition is rejected as nonsensical and replaced with the actual definition of risk.


I'm separating cost vs. risk and you're not; when you correctly factor that difference in: 200k < 0 + 2b, or 200k > 2b -2b

Whichever you prefer, it's all perfectly consistent.


You're using the collquial or informal meaning of "risk" whilst Tippia is using the actuarial version. The effect is much the same as Creationists saying Evolution isn't proved because it is "just a theory".

Nevertheless it is obviously ludicrous to say that a 99% chance of losing a ship to CONCORD is more of a deterrent or a cost than a 100% chance of losing one.

tl;dr: there is a such thing as a "100% risk" and it's you who are being obtuse in arguing that there isn't.

Just because the probability is 1 doesn't mean it's not a risk — it just means that the risk is so hight that it has the same value as the cost.


Too lazy to read the entirety; are you still arguing that suicide cats (which work out to about the isk/hour of BS ammo) are inherently risky?

Like most people, I tend not to factor ammo costs into my risk assessment.

You are correct. When suicide ganking the ship is the expendable ammo. A risk is not a risk if the outcome is certain. A risk requires an element of chance.

So there is no risk in ganking. Just expenditure.

The risk in ganking is that the target lives. We minimise that risk by knowing what we are doing, but it doesn't mean the risk isn't there. Just yesterday someone jumped the gun and nearly got us all rapidly killed before out target dropped. We literally got it just as the last ship popped. I've seen many less experienced gank squads fail to execute a gank, or get blapped off the field too quickly to finish it. I've also seen ECM ships suppress a gank enough to save the target ship.
If you fail a gank, you are stuck with a blown up ship and a GCC with a failed objective. That's the risk.

And it's no different from the mining risk. I've NEVER had a miner ganked in high sec, even though I've run many a mining operation. Careful choices of location and a keep eye out for gankers and scouts can minimise the risk there too.

So the long and short of it is, don't mistake well performed actions with risk purposely minimised as being inherently risk free activities.

AFAIK mainstream physics says yes; it falls out of uncertainty.

Less so than cost since there are associated probabilities.

I can see how you might think that, given all the fancy words she's throw out haphazardly. However, I found her preferred source:

The ISO 31000 (2009) /ISO Guide 73:2002 wrote:
definition of risk is the 'effect of uncertainty on objectives'. In this definition, uncertainties include events (which may or may not happen) and uncertainties caused by ambiguity or a lack of information. It also includes both negative and positive impacts on objectives. Many definitions of risk exist in common usage, however this definition was developed by an international committee representing over 30 countries and is based on the input of several thousand subject matter experts.


Also, your example is inappropriate since we're talking about the same thing and quibbling over semantics whereas Creationists dispute events.

OK well I'll cut to the chase: There is no traction for a change in the rules for suicide ganking regardless of whether 100% chance of shiploss is or, in whargle-garble land, is not less of a deterrent.

If people want to keep trotting out the rhetorically dishonest "no risk" line when what they're plainly trying to imply is that there's no cost to suicide ganking (That cost being something that the "no risk brigade" never fail to either neglect altogether or blatantly lie about the magnitude of) then their arguments and indeed their wishes will be treated with the derision and contempt they deserve.

I'm not. Anyway, if an international standard for risk is not your cup of tea, just look at the wiki summary, which a bit further down provides the quantitative analysis version, which is just risk = cost × probability.

The shocking part of the ISO standard these days is that it does away with the word “cost” or “loss” in exchange for “outcome” so it doesn't sound as negative, and so that it's easier to conceptualise negative outcomes (gains, if viewed from a loss perspective, losses, if viewed from a gains perspective).

Quote:

They're no more (or less) associated with probabilities than costs are. Common language use has just taught you to “don't count your chickens” and to equate “risk” with “uncertainty”, which has led you to think of both all positive outcomes and all risks as being uncertain, when neither is strictly true.

Meanwhile, how about this for a gank risk assessment:

∑ cₓpₓ - (∑ cᵢpᵢqᵢ)׃(σₓ)

…where cₓ is the cost of the ship and fittings, pₓ is the probability that they're lost in the process, cᵢ is the cost of the item, pᵢ is the probability that the item survives, qᵢ is the probability that the item is not stolen, and ƒ(σₓ) is the probability of the gank succeeding as a function of all the ships involved. All these probabilities are <1, by the way so in the end, it doesn't even matter if you reject p=1 as qualifying as risks. Blink

You're thinking too deeply about this IMO. On one hand I applaud you for that, but on the other hand one must be realistic in understanding how these concepts apply off the paper.

Death as a ganker is in fact inevitable. It's like saying driving a car at 200 mp/h through a red light has a risk of making you run a red light. It is in fact impossible to not run the red light. Through numbers you could have a "risk factor" of 100% but as we come back to reality, the definition of risk inherently involves two potential outcomes that are both plausible. Thus in this scenario using the word "risk" is a rather improper term.

Thus I object to the manner in which you are measuring risk/reward. There is a big difference between risk and chance. Risk involves the potential for loss by definition. There is no potential here, the loss is objective and static.

That's how you calculate it (or at least the standard version), but formulas aren't always applicable.

It's more an issue with timing. I consider the decision made when the cost is paid, making that certain. The outcome/profit, a future event, is never certain - at least not from our frame of reference.

I'd simplify out pₓ if you're letting it equal 1; also the item can't be stolen if it doesn't drop, making pᵢ and qᵢ dependent so you can't multiply them.

In any case, you've lost a lot of information by simply extracting the expectation; information that's important in balancing activities.

Actually, it is in fact not, especially once you start going into actual, traditional gangks.

Exactly: risk is not the same thing as chance, which is why risks are still risks even when the outcome is certain.

Again, risk = cost × probability, and that cost does not have to actually be a loss, and the probability doesn't have to be <1.

…which is why it measures “not stolen” as opposed to “stolen”. If you wanted to simplify anything, it would be pᵢqᵢ into p[actually getting the goods]. Then again, that part is admittedly timing-based — I suppose we could complicate it further with the odds of the pick-up ship being (counter)ganked, which means we have a pₓ for x=hauler in there as well.

I don't think they are interested in anything like that. They are just interested in trying to make the most amazing looking post while all essentially being completely off topic, even if the topic was about risk. They are pretty much debating the definition of risk, when all they really need to be concerned about is where there is a chance of failure on both sides, to which the answer is obviously yes, thus rendering everything else they say on the subject pointless. Quantifying the risk on each side would have so many variables that each situation would be unique, and the argument started as "ganking is 100% risk free" which is an obvious troll, or an incredibly stupid poster. Either way, not worth discussing.

Still dependent (unless you have some weird definition that's not = 1-P[stolen]); have no problem with P[actually getting the goods] though.

If you prefer: suicide ganking is too easy/low cost/profitable - certainly worth discussing.

As for the book: I have trouble taking anything that uses the word philistine in a derogatory manner seriously, but I do read a fair bit of philosophy.

No. A risk only requires an outcome (usually a cost) and a probability. Just because the probability is 1 doesn't mean the risk goes away.

Yes but lets be realistic here. When the probability falls so low its not a discernible factor there is little to no risk to the person ganking. But if you like than I'll say

"The risk experienced by suicide gankers blowing up miners in barges and so on is so low it could be considered non-existent for anyone not super pedantic".

Does that satisfy you?

I disagree. I have done it too. The reward is having killed someone and made them rage. This is probably the most rewarding thing you can get in EvE in my experience.

There's plenty of risk. We've only gotten started with the first false notion: that the ship loss itself isn't a risk (when the reality is the exact opposite). We haven't even begun to touch the parts that create risk in terms of the pay-off.

Quote:

No, because it still wilfully or ignorantly disregards all the risk involved. Try this on for size instead: “The risk experienced by suicide gankers blowing up mining barges and so on is determined by their picking targets where the projected gain is suitably higher than the projected loss and even then, there's the risk of finding no suitable targets.”

Risk does not preclude there being a guaranteed loss.
Risk does not preclude there being a projected net gain.
