A Defense of the Biological Basis for Intelligence

biology genetics neuroscience intelligence IQ

Intelligence Quotient, or IQ, is supposed to be a measure of a person’s ability to reason, see patterns, and make predictions. Yet IQ is quite controversial – a controversy ranging anywhere from IQ tests being inaccurate or biased and all the way to IQ tests (and anything concerning IQ) being immoral. Yet, even if there is no test that can accurately and reliably gauge an individual’s intelligence in some quantitative way, most people are aware of some ineffable sense in which some individuals are just smarter than the average individual (and vice versa with some people just being less smart in some ways than other people).

Quantum Computers, Shor’s Algorithm, and Post-Quantum Cryptography

Want to know how quantum computers really work? And why they can crack our best encryption systems? And how we might combat this? In this post, which is from a paper I wrote for a cybersecurity class where I went a bit above and beyond the assignment, I will go over these things. This post is long, but if you are interested in this, you might find it rewarding.

Is Value Neutrality Possible?

/ Thomas Harper / Leave a comment
(Source)

Objectivity, also known as value neutrality or impartiality, is one of the highest ideals of science. The principle behind it is that science studies mind-independent reality, i.e., that which continues to exist even if no consciousness is there to perceive or think about it. This mind-independent reality is devoid of all values – there is no such thing as “good and bad” or “useful” or “beautiful” when it comes to, say, galaxy formation or evolution by natural selection. A major criticism of science levied by critical theory is that value neutrality is impossible, even if we are to take the assumption that mind-independent reality exists and that mind-independent reality is value neutral. As such, instead of blinding ourselves to the values and biases that are inextricable from science, we ought to import the “correct” values into science (e.g., feminist science).

A Metamodern Argument for Designer Babies?

I have written a very lengthy review of The Listening Society: A Metamodern Guide to Politics, Book One (Metamodern Guides), by Hanzi Freinacht. Because it is so lengthy, it will probably have very few people who read the entire thing. But an argument I made in my review of the final chapter is something interesting that I thought deserved some of its own consideration, and so this post is adapted from my review of the final two chapters in The Listening Society. Keep in mind that although it is not a necessary requirement to have read my review of all the prior chapters to understand this post, it would be helpful.

What is a Scientific Theory?

/ Thomas Harper / 10 Comments
scientific theory in science

Scientists and science enthusiasts can get exasperated by the conflation of definitions between the scientific conception of a theory and the colloquial definition. In the latter, a theory is sometimes considered no better than a guess, and at best what a scientist would call a hypothesis (an educated formulation of a mechanism or explanation). People will say things like “evolution is just a theory” as if that attests to some shortcoming of evolution. In the scientific conception, a theory is the gold standard. It is a set of inferences, explanations, predictions, and interpretations that bring together (sometimes disparate) data, evidence, and observations into a cohesive whole. Theories are what scientists use to make predictions in order to formulate new hypotheses and design new experiments. But what is the nature of a theory? And what is the ontological status of a scientific theory? In what way is a theory true?

Trust the Science?

/ Thomas Harper / 1 Comment
trust the science

A common refrain in the news media during these COVID years has been to “trust the science.” This is also a popular mantra when it comes to climate science. Yet, in the United States at least, trust in experts and institutions is at an all time low. The political right is skeptical of climate science, COVID vaccines, and scientific institutions like the NIH and CDC, seeing them as a means for the government to take away rights and for liberals to impose their will. The political left views science as a white colonialist means of subjugating those with other “ways of knowing” and upholding white, male privilege. So the question is: should we trust the science?

Woke Science: a Toxic Marriage of Activism and Science?

/ Thomas Harper / 8 Comments

In science, objectivity is the greatest virtue. In an ideal world, a scientist would be impartial, disinterested in the outcomes, never desiring one result over another. They would run the experiment, gather the data, and report the findings, even if the data showed something that refuted the scientists’ hypothesis or gave an uninteresting negative result. Experiments would be replicated by multiple different people to more rigorously determine the veracity of the results. Negative results would get published as often as positive results. Topics for study would be determined by a mixture of intellectual curiosity and potential for improving society in some measurable way. Science, to say the least, does not live up to this ideal. But is science redeemable?

Is the Human Brain a Computer?

/ Thomas Harper / 1 Comment
brain computer

The popular, even ubiquitous metaphor used in cognitive neuroscience is that the brain can be likened to a computer. The similarities seem obvious: neuronal activity is binary (a neuron is either depolarized (ON) during an action potential or polarized (OFF) when inactive); our vision and hearing has many aesthetic similarities to a computer display (indeed, the monitor is made exactly to fit the human experience of colors, shapes, etc.); humans process information (we can sit down and think through a math problem, for instance). So on and so forth. But is the “brains are computers” metaphor accurate? And if not, then is adherence to this metaphor slowing down progress in neuroscience?

Integrated Information Theory and Cosmology

/ Thomas Harper / Leave a comment
information universe simulation theory

Information can be broadly defined as the reduction in uncertainty. The reason that the location and momentum of 100 particles in a 1×1 meter box contains less information than either A) the location and momentum of 100 particles in a 10×10 meter box or B) 1,000 particles in a 1×1 meter box is because, in case A, one must specify a greater number of microstates (i.e. there are more possible arrangements of particles) and in case B, there are more particles whose position must be specified. What can we say about cosmology using the integrated information of all particles in existence?

Life on Venus: Proposed Biochemistry of Venusian Life

/ Thomas Harper / Leave a comment

The possible detection of phosphines in the atmosphere of the planet Venus has sparked interest in possible biogenesis of the compound. In other words, there may be microscopic extraterrestrial organisms living up in the Venusian clouds. This would be an amazing discovery. But, it also raises the question about what sort of biochemistry such organisms (if they exist) utilize in their Venusian flavor of metabolism. Here I will make some speculations about this.
