Save the official lab report for your colleagues; now is the time to engage laymen by telling a story about your science experiment in human, vivid and colorful terms. Assess your audience to help you make smart decisions about how to word your essay.
Allan Crossman calls parapsychology the control group for science. That number tells you how many people will recover whether the drug works or not. That number tells you how many studies will discover positive results whether the phenomenon is real or not. Trying to set up placebo science would be a logistical nightmare.
The results are pretty dismal. Parapsychologists are able to produce experimental evidence for psychic phenomena about as easily as normal scientists are able to produce such evidence for normal, non-psychic phenomena.
As Eliezer Yudkowsky puts it: Parapsychologists are constantly protesting that they are playing by all the standard scientific rules, and yet their results are being ignored — that they are unfairly being held to higher standards than everyone else.
It just means that the standard statistical methods of science are so weak and flawed as to permit a field of study to sustain itself in the complete absence of any subject matter.
These sorts of thoughts have become more common lately in different fields. Psychologists admit to a crisis of replication as some of their most interesting findings turn out to be spurious. And in medicine, John Ioannides and others have been criticizing the research for a decade now and telling everyone they need to up their standards.
But there is broad agreement among the most intelligent voices I read 12345 about a couple of promising directions we could go: Demand very large sample size. Demand replication, preferably exact replication, most preferably multiple exact replications.
Trust systematic reviews and meta-analyses rather than individual studies. Meta-analyses must prove homogeneity of the studies they analyze.
Use Bayesian rather than frequentist analysis, or even combine both techniques. It is far too easy to massage p-values to get less than 0. Require pre-registration of trials. Do heterogeneity analyses or at least observe and account for differences in the studies you analyze. Demand randomized controlled trials.
Stricter effect size criteria. Well, what now, motherfuckers? Everyone had a lot of criticisms, some of which were very very goodand the study failed replication several times.
By my count, Bem follows all of the commandments except  and .
And he apologizes for the small effect size but points out that some effect sizes are legitimately very small, this is no smaller than a lot of other commonly-accepted results, and that a high enough p-value ought to make up for a low effect size.
This is far better than the average meta-analysis.Part I: Introduction--What inspired my argumentative response? For decades, too many high-school teachers have been instilling persuasive writing skills by teaching students the five-paragraph essay.
If the exploratory and discovery nature of science captivates you, there may be no better way to share your enthusiasm than to write an essay about a science experiment and share it with others.
Video games depict a variety of different concepts. Models of learning in games like the GLM (General Learning Model) and GAM (General Aggression Model) predict that exposing players to these in-game concepts can lead to important changes in player behaviour.
On this week’s show: the latest social science replication study, the mechanisms behind human-induced earthquakes, and Judea Pearl and Dana Mackenzie’s The Book of Why: The New Science of. RubiStar is a tool to help the teacher who wants to use rubrics, but does not have the time to develop them from scratch.
Photosynthesis is one of the fundamental aspects of biology. You can do this fun photosynthesis experiment using leaf discs to better understand how it works.
