The first is the success of antivivisection campaigners in lampooning animal research as outdated, intentionally cruel, "bad" science, which achieves nothing. All drugs and procedures developed with the help of animal tests are said to be dangerous. The occasional failure of animal testing to identify a dangerous drug is developed as an argument for abandoning safety tests involving animals altogether--with no mention of the terrible human suffering that this would cause. They say that "alternative" methods already exist for all animal experiments, but the fact is that the law specifically forbids animal use if there is any alternative. The second reason is that scientists and doctors have failed to oppose such misrepresentation. In the early 1990s, animal rights campaigning in the US was met with much more forthright defense, not only by the major scientific societies, funding agencies and medical organizations, but also by the US government. To be positive, there are many encouraging features of the New Scientist poll. Interestingly, the public seems to employ the same kind of utilitarian philosophy that underpins the law in Britain--weighing potential benefits against the species involved (thus, monkeys are more "valuable" than mice) and the likelihood of suffering. Clearly, people in Britain do not recognize the essential link between animal research and testing and the medical treatments that they receive. Only 18 percent of those who had taken (or had a close family member who had taken a drug prescribed for a serious illness realized that the drug had been tested on animals, as all drugs are. Obviously, a large majority of those surveyed believe that they can happily benefit from medical treatment without taking advantage of animal research. No wonder so many people oppose it when asked the straight yes/no question. The views of the public must be respected. But this poll tells us that, while they are open to persuasion, their reaction is based on misunderstanding. The responsibility for providing honest evidence for the public lies not just with those who use animals in their research, but with other scientists who depend on that work. It lies with the doctors who benefit from animal research, with the pharmaceuticals and biotech industries, and the medical charities and funding age, les whose work would be crippled without it. But most of all, responsibility rests with government, which should cultivate serious and transparent debate between those of different opinion, and provide the public--especially young people--with the honest evidence they need and deserve.

E.J. Masicampo and Roy Baumeister of Florida State University discovered this by doing some experiments on that most popular of laboratory animals, the impoverished undergraduate. They asked 121 psychology students who had volunteered for the experiment to watch a silent video of a woman being interviewed that had random words appearing in bold black letters every ten seconds along the perimeter of the video. This was the part of the experiment intended to be mentally taxing. Half of the students were told to focus on the woman, to try to understand what she was saying, and to ignore the words along the perimeter. The other half were given no instructions. Those that had to focus were exerting considerable serf-control not to look at the random words. When the video was over, haft of each group was given a glass of lemonade with sugar in it and half was given a glass of lemonade with sugar substitute. Twelve minutes later, when the glucose from the lemonade with sugar in it had had time to enter the students' blood, the researchers administered a decision-making task that was designed to determine if the participant was using intuition or reason to make up his mind. The students were asked to think about where they wanted to live in the coming year and given three accommodation options that varied both in size and distance from the university campus. Two of the options were good, but in different ways: one was far from the campus, but very large; the other was close to campus, but smaller. The third option was a decoy, similar to ope of the good options, but obviously not quite as good. ff it was close to campus and small, it was not quite as close as the good close option and slightly smaller, if it was far from campus and large, it was slightly smaller than the good large option and slightly farther away. Psychologists have known for a long time that having a decoy option in a decision-making task draws people to choose a reasonable option that is similar to the decoy. Dr. Masicampo and Dr. Baumeister suspected that students who had been asked to work hard during the video and then been given a drink without any sugar in it would be more likely to rely on intuition when making this decision than those from the other three groups. And that is what happened; 64% of them were swayed by the decoy. Those who had either not had to exert mental energy during the showing of the video or had been given glucose in their lemonade, used mason in their decision-making task and were less likely to be swayed by the decoy. It is not clear why intuition is independent of glucose. It could be that humans inherited a default nervous system from other mammals that was similar to intuition, and that could make snap decisions about whether to fight or flee regardless of how much glucose was in the body. Whatever the reason, the upshot seems to be that thinking is, indeed, hard work. And important decisions should not be made on an empty stomach.

2. If man's mind cannot be turned into a logic-machine, neither can it function properly as a great emotional sponge, to be squeezed at will. All of us have known people who gush as a general response to life——who gush in seeing a sunset, who gush in reading a book, who gush in meeting a friend. They may seem to live by emotion alone, but their constant gushing is a disguise for absence of genuine feeling, a torrent rushing to fill a vacuum. It is not uncommon to find beneath the gush a cold, analytic mind that is astonishing in its meticulousness and ruthless in its calculation. Somewhere between machine and sponge lies the reality of the mind——a blend of reason and emotion, of actuality and imagination, of fact and feeling. 3. The entanglement is so complete, the mixture so thoroughly mixed, that it is probably impossible to achieve pure reason or pure reason or pure emotion, at least for any sustained period of time. 4. It is probably best to assume that all our reasoning is fused with our emotional commitments and beliefs, all our thoughts colored by feelings that lie deep within our psyches. Moreover, it is probably best to assume that this stream of emotion is not a poison, not even a taint, but is a positive life-source, a stream of psychic energy that animates and vitalizes our entire thought process. 5. The roots of reason are embedded in feelings——feelings that have formed and accumulated and developed over a lifetime of personality-shaping. These feelings are not for occasional using but are inescapable. To know what we think, we must know how we feel. It is feeling that shapes belief and forms opinion. It is feeling that directs the strategy of argument. It is our feelings, then, with which we must come to honorable terms.
