Hehe, this is the kind of question I ponder and discuss with colleagues every week...there are no easy answers

1) Is it right to continue with a particular area of research in the knowledge that it could engender considerable harm?
Here I agree with Morril: The major problem is that it's most often impossible to predict whether certain knowledge will have more benefits than dangers, and many of the major discoveries in science are made serendipitiously, ie they were not predicted and scientists did not intentionally look for that particular discovery.
Almost all knowledge can be used in a harmful way, as tools for destructive and immoral acts or as propaganda by inhumane ideologies. For instance, if we study Germany during the 1930's, we can learn both how to avoid and how to create a highly discriminative society. If we study genetic engineering, we can learn both how to cure some of mans most painful diseases, and how to create an elite society with people selected for certains traits.
2) Another question I have often pondered is that of academic 'objectivity'.
I am not denigrating the wealth of research that has contributed to our understanding of the world about us. But, I do question the perception that such investigation is entirely "objective." Everybody, is influenced, to some degree, by their cultural beliefs. And often, academic and intellectual thought directly mirrors the prevailing currents of a certain era... Or much worse.. sometimes heinous ideologies are justified beneath the guise of academic respectability....
The objectivity of science lies in the scientific method. What you can easily corrupt though, is the circumstances for science to exist in. Science do not exist in a vacuum but in a society, and although the scientific method is designed to exclude the scientist's own personal opinion, feelings or beliefs, it is not difficult to construct a social structure where science is impossible to conduct.
Here at SYM I have many times answered questions regarding whether a scientists is affected by personal belief and also answered various assumptions that science is a faith in the same manner as religion. Because of this I have previosly posted definitions of what science is, so forgive me for repeating myself, but here we go again:
Science is a strategy to gain knowledge and understanding about natural phenomena by systemised, repeated observations and experiments.
This website
http://teacher.nsrl.rochester.edu/phy_l ... ndixE.html
has a good basic introduction to what science is:
1. Observation and description of a phenomenon or group of phenomena.
2. Formulation of a hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation.
3. Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations.
4. Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.
This little online book also has a nice introduction to science on page 1-11, and if you follow the link you will see a chart-flow of how science is conducted.

So, the scientific method in itself really minimize the influence of the scientist - I can't change the outcome of my experiments with pure willpower. I would very much like to find a pharmacological compound that decrease the cognitive impairment I see in demented patients, but so far, this wish has neither made their test results better, nor made their brain cells grow in number. Also, when my Japanese, American, French or Canadian colleagues repeat the same experiments as we do, they don't find any improvement either. It doesn't matter what my hopes and wishes are, what my personal opinions are, what my hypothesis and my predictions are or what personal biases I might have: the measurement equipment I use will register the same values regardless of me. The only thing I can do is to introduce
non-scientific events in the measurement process (ie I can manipulate the equipment) or falsify the data (ie I can ignore the values I get and instead put in figures I like better). But this is not science. This is not the scientific method. This is just me being a corrupt person.
So, let's presume I falsify my data or that I simply get measurements error due to faulty equipment. Still, that doesn't change what is going to happen when my colleagues all over world repeat my experiment during the same condition, and find totally different results.
Replication, ie independent repeating of the experiment and getting the same results, is a fundamental part of science. My lab may have made a measurement error, but it's not so likely that 100 other labs will have the same error.
"Morton was no Southerner defending slavery, but a Philadelphia physician engaged in basic research. He established in Philadelphia the world's largest collection of human skulls. <snip> Although Morton based his conclusions on physical comparisons, he was also deeply impressed by historic Caucasian achievements and by the evidence of separate human races three thousand years before in Egypt.
<snip>
Enter Dr. Phillip Rushton. Currently a professor in psychology in the University of Western Ontario, Rushton's controversial history began when he presented a paper at the Symposium on Evolutionary Theory, Economics, and Political Science in 1989. He classified all human beings somewhere among the three major racial groups: Black (Negroid), White (Caucasoid), Asian (Mongoloid). He claimed to have scientific evidence of an inherited link between brain size, intelligence and race, where Blacks and Asians are on opposite ends and Whites are in between.
This is two examples of non science, or bad science. Being a professor in psychology doesn't mean your subjective personal opinions are any more scientifically valid than the man on the street's personal opinions.
Morton makes a taxonomy of racial groups based on skull morphology, then he attaches his subjective values to these groups. Ok, I can make a taxonomy of life forms based on colour, then I can attach my personal colour-taste to it. Red is my favorite colour, so corn snakes, robins and starfish are more worth and better life forms than vipers, humans or sharks. However, in order to make science out of this, I must first formulate a testable hypothesis and I need to make an operational definition of what constitutes a "better life form". In order to test for what is better or worse life form, I must construct measurement instruments, and those must be validated and tested for reliability. There you can already see how problematic it would be to make science out of this.
Rushton's paper on the other hand can be labeled as non-scientific or as bad science, depending on circumstances. (I made search, and found out that it was presented at the meeting you mentioned, but it has never been published in the peer-reviewed press. That alone is reason enough to be suspicious - not even the most established meetings scrutinize papers in the same manner as the peer-reviewed press does, and this is simply because symposia and congresses are aimed to be more open - places for testing of new ideas, discussions, brain storming etc.) Anyway, for many years, white Europeans and Americans had significantly higher IQ than black Americans. However, also few totally scientifically unedcuated people are so stupid so they don't realise there are
other factors than intelligence, ie background factors and co-variating factors, that contribute to the data aquired. Already in the childhood of IQ-measurements, it was known that level of education played a role, although it was not known how large.
I am not familiar with Rushton's work, but it sounds similar to the infamous "Bell curve" and if it has similar flaws, ie failing to address such basic issues as correlations are not the same as casual explanation and use of only a few selected factors and ignoring other factors, then it is not even bad science, then it is just not science. Non science does not become science because the person performing it is a scientist. Einstein having dinner with Crick is not science because they both worked as professional scientists
