Yes, assumptions are always wrong.** Deduction is another matter.** :)
TLK, thats I want I prove to this forum, you said "I make few assumption based on my engineering judgement", **you are not assumming things but you are deducing things because of your engineering jugment. **Tell that to AQ and Intelli that, and I am still waiting for the statements from the dictionary. :)
Well said,
I guess we engineers use the word assumption out of habit and maybe word deduction has more afirmation to it and saying ' I made the wrong assumption' vs **'I made the wrong deductions' **sounds better if you realize and analysis error ..
Very interesting ... So initially assumptions to deduction because deductions are not wrong as assumptions and then, while agreeing with each other, statment comes to say that deduction is made wrong too... LOL
Most scientific disciplines are based on the premise of assumptions. In my own area of work of business decision modeling and social science research, assumptions are a part of the routine. These assumptions are usually based on prior research through which certain generalizable essentials have been derived. These generalizations are typically scrutinized and often challenged by the research community at large on the basis of the robustness of research procedures and/or proof lemmas and corollaries.
Like TLK said, pretty much the whole field of simulation is based on assumptions and generalizations.

I am not sure what I said in the second post .... but the first one is what I wanted to say for sure ...
I guess here is what I wanted to say to your first post ..
assumptions can be correct but you dont know if they are correct when you are making them .. that is why they are called assumptions ..
deduction is more of a logical conclusion. I guess that means you had all the facts, so a wrong deduction can be more dangerous than a wrong assumption.

100% on the mark, u have to base your hypothesis on assumptions. Even in my area of classic strategic mgmt consulting, you are starting out with a hypothesis that is based on a set of assumptions, and then you test those assumptions with the outcome being if the assumptions pass then your move forward, if they fail then you dont. If you are in an industry for some time and keep up with trends, majority of your assumptions will come out to be true.
Intelli, I am trying to be a teacher now and starting a business towards it, usually I tell my classmates who are at the beginning level to start from their class room books. And that comes to our dictionionary theory. How can I explain to my point if you don't know the meaning of assumptions and deductions. AQ, asked assumptions are always wrong, I said yes because they usually do. But deductions are another matter because they are can be wrong or not wrong.
If the apple fell on Newtons head you will call it an assumption that he made it it a hypothesis and started saying Eureka meaning that I have found it. Its his scientific judgment which made made him deduce the fact that theory of gravity which we call a theory now. Look what Lucid said "These assumptions are usually based on prior research through which certain generalizable essentials have been derived.". Look what X2 said *"you are starting out with a hypothesis that is based on a set of assumptions, and then you test those assumptions with the outcome being if the assumptions pass then your move forward, if they fail then you dont." *They are not assumptions but they are deductions. In Lucid case was scientific and X2 case was management. Deducing the fact that this theory will not work or will work according to their experiences and judgement.
So Intelli and AQ, start with your class room books and open the dictionary up. :)
wiseman, but aside from semantics, there will be no deductions if there were no assumptions, u decuce that an assumption was infact right. u dont test your deductions you test your assumptions. The testingf of your assumptions results in deductions, and btw just like your assumptions can be incorrect, your deductions can be faulty has well :).. assumption is synonymous with hypothesis, theory..or even a guess. you can guess correctly or you can guess incoreectly or you can guess ciorrectly.
I am not sure how we can seperate deduction from assumption anyways. :)
AQ-it depends, what one thnks as facts may or may not be relevant. I can not base assumptions on market potential of a product based on a set of facts from 3 years ago, industry has moved, products have moved, economy has changed, consumer base and opinion may have shifted.
in the end, even if someone has facts and they are valid, it does not mean that the assumptions based on those would not be tainted by the opinion and bias of the person assessing the situation. facts can be spun. analysis paralysis is a real handicap at organisations with a lot of focus on the rear view mirror versus finding a balance.
in teh end the question is what does one do with the set of assumptions. IN y line of work where I have to assess market potential of new ideas, I have to put them thru the paces very quickly to se whether I will need to bother detailed assessments or focus on other better challenges.

That's precisely why one needs to differentiate between a priori propositions vs. a posteriori propositions... and also between analytic assumptions and synthetic assumptions. Combine these two dimensions, and you get a nice 2x2 :) - don't we all just love'em...
agreed... you need to contextualize these within the frame of your inquiry and be reasonably sure that they make logical sense.
you being a consultant have probably seen it as you have been called in to review business cases developed by personnel at client companies. Assumptions supported by seemingly valid set of facts, but either incomplete fact set or drawing conclusions which are not fully supported by the available fact set, risks not fully identified and getting in hot water due to that.

analytic a priori
analytic a posteriori
synthethic a priori
synthetic a posteriori
whoa whoa..rolling out heavy stuff. dont be going all imannuel on me brotha..just dont get into metaphysical aspects and how knowledge of synthetic a priori propositions is made possible

haha... I know man... and that's why I stopped at the 2x2 without further elaboration. For me personally, I think a priori and a posteriori is a good enough approach to assumptions... something you know by definition vs. something you know by observation. Typically its a hybrid of these that we use in our personal and professional lives.
Is our discussion getting into some vicious circle?
assuming or deducing if facts are relevant or not. hmph…
Pardon me, initially, my question was more of a common man’s life related, not some politically corrected vision for group of high class professinals and/or Ph.D’s.

true that! and on a similar note, on the research front, we always report the limitations of a study because often the assumptions may not be generalizable to the data that is available.
