Manifest Of the Cult of Stat-Normalization?
Quote:
The stats in GURPS are meant as most people having 10 in a given attribute - most, which means, more than half. Take a group of 100 people, and at least 51 will have a score of 10, not more, not less. Additionally, the remaining, higher attributes will be increasingly rare - while another 20% might have score 11, only 5 or 10% might have 12, etc. Hm. Does not look complete. Additions?

Though that literal a translation does not really work for GURPS, and indeed cannot. For one thing, consider IQ. You would have to say that 10/216, or just about 5%, had IQ 5 or less—which is defined as nonsapient: equivalent to mammals (other than great apes) or birds, and incapable of language use. That's a hopelessly implausible model of the human population. At the other extreme, I don't think most stat normalizers would be happy with one person in twenty having IQ 16-18. In any case, whatever distribution you adopt for the general population need not apply to player characters. Pretty much by definition, player characters are exceptional. I am probably a stat normalizer by basic inclination. At least, I worked with such an approach when I was contributing to GURPS Who's Who. But I didn't try to make a bunch of notable historical figures fit onto a Gaussian distribution. What I did was more in the way of making their stats exceptional to the minimal degree needed to describe them: an 11 or 12 would become visible over time to anyone who knew the person, a 13 or 14 was obvious and would be a big influence on the person's life and career choice, and a 15 or 16 was rare and extraordinary, while anything beyond that was almost unheard of.

Re: Manifest Of the Cult of Stat-Normalization?
I'd like to hear more from the stat normalizers. I *think* I fit into the category, but am not sure. Great point about IQ. What are the stat ranges of the normal human population if you assume a Gaussian distribution?

Re: Manifest Of the Cult of Stat-Normalization?
If we're talking bell curves and The Cult, I'd summarize the position as this:
GURPS stats (with the possible exception of ST) are distributed roughly in a bell curve with a sigma of one. (This applies to healthy young/middle aged individuals, not kids or old people, who have different means). This gives the following stat distribution in the population: 7- 0.1% 8 2.1% 9 13.6% 10 68.2% 11 13.6% 12 2.1% 13+ 0.1% Practically, this means that a stat difference of 1 is significant, a difference of 2 is obvious, and a difference of 3 or more is extraordinary. The most co-ordinated person from a random sample of 10 will have DX 11. The healthiest person in a medical study of 250 folks will probably have HT 12. The smartest person in your 1000 person high school is IQ13. Further numbers - one reason I dislike the bell curve for practical Cult apps is the far stats: 14 0.003% 15 0.00003% 16 0.0000001% 17 0.0000000001% (etc) I personally prefer to skip the annoying tables and oversharp tail off for: 10: 78% 11: 10% 12: 1% 13: 0.1% 14: 0.01% . . . This is easier to remember and makes estimating how rare a stat is easy. Smartest person on Earth? Somewhere between 1 in 10^9 and 1 in 10^10, so IQ19-20. Works out nice. That said, no one says you have to follow The Cult. Really, IMHO, it is mostly useful to make GURPS Mundane Folks work out better. If, like most gamers, you play GURPS Wild Crazy Far Out Heros, just don't worry about it. martinl |

IQ test problems are fairly straight-forward, standardized, normalized and built so you can find a solution. Real life is much, much more chaotic. There are tons of irrelevant data that comes with everything, part of GURPS IQ is filtering that to get to the core of the problem. Most of the time you don't have enough information and have to act on probability you instinctly calculate, not cerainty. And sometimes God just throws the dice right into the black hole. While it is safe to say that someone with a big IQ score IRL might have a higher IQ in GURPS, it's not absolutely certain, as that sort of score is just one of the atributes of GURPS IQ. Formulas will not work, because we don't have, and probably can't have, all the factors of GURPS IQ pinned down. I say this as both a gamer and a psychologist. Real life doesn't find much use for IQ tests too, americans seem to be fixated on it, most other countries in europe and south america have left it to very specific uses and the population couldn't care less what your IQ is, that includes companies that are looking to hire, universities looking for teachers, etc...

ST and HT are different, with a much larger range of normal human values. |

The Cult says that point optimized character creation is extremely unrealistic, specifically with respect to high stats. Note that The Cult does not require you to build realistic characters (although this is a very common opinion in The Cult), it just mocks you if you call non Cult Doctrine characters "realistic." Corollary: <Stat distribution stuff earlier in thread> Corollary 2: If you want to be really good at something, take a Talent and/or a bunch of related advantages. The Cult's main opposition is the Conclave of Point Optimization, which states: (In GURPS character creation) it is perfectly realistic to raise a stat rather than skills if that would save points. This represents the fact that you are exercising your (brain/body) enough you see overall improvement. Corollary: It is often quicker and almost always more efficient to represent talent with high stats rather than acual Talents and other fiddly advantages, especially for adventurers, who need broad areas of expertise. So your gun-fu ballerina acrobat Cult style: Dex13. Other stats 9-11. Dance talent. Very fit. Lots of points in skills. Your grizzled WWI vet Depression era PI Cult style: HT and Will 12. Other stats 9-11. Combat reflexes. Lots of points in lots of skills. So your gun-fu ballerina acrobat Conclave style: Dex16, HT 14. Other stats 11-12. 1-2 points in each skill. Your grizzled WWI vet Depression era PI Conclave style: HT, DX and Will 14. Other stats 12. Combat reflexes. A few points in several skills. (Note that DX 14 is not part of the concept, but is cheaper than buying all the combat skills up instead.) Hope this helps, martinl Who now want's to play a Gun-fu Ballerina Acrobat Last edited by martinl; 05-01-2007 at 10:28 AM. |

Re: Manifest Of the Cult of Stat-Normalization?
I would say that a major issue for stat normalizers is IQ. Frankly, the GURPS IQ stat does not correspond to any discernible real-world trait; no-one is that broadly competent in multiple areas. In particular, academic talent and social talent, outside of certain types of mental retardation that affect both, don't show much evidence of real-world linkage at all.

The point I was making was quite narrow: If you roll 3d6, they have a certain statistical distribution that conforms fairly closely to a Gaussian normal distribution and that has a computable standard deviation of around 3.0. The resulting translation of p.t. IQ into GURPS IQ further evidences my claim in a previous post that "that literal a translation does not really work for GURPS, and indeed cannot." If you actually take the time to read my various posts carefully, you will find that they reflect a consistent overall view of the matter, which does not actually disagree with your assertions.
