The authors emphasized that the findings reflect a problem that affects all of science and not just psychology, and that there is room to improve reproducibility in psychology. In 2021, the project showed that of 193 experiments from 53 top papers about cancer published between 2010 and 2012, only 50 experiments from 23 papers could be replicated.
The Psychology Today article generated enormous publicity for the experiments, which are well known today, long after much of the formative work has been forgotten. Milgram's experiment was conceived in an era when a number of independent threads were converging on the idea that the world is becoming increasingly interconnected.
The 1948 experiments inferred reproductive success based on the number of adults living by the end of the trial. In reality, many factors were left out of the equation when calculating reproductive success as a function of the number of mates, which had the ability to completely dislodge the accuracy behind Bateman's results.
Psychology Today is an American media organization with a focus on psychology and human behavior. The publication began as a bimonthly magazine, which first appeared in 1967. The print magazine's reported circulation is 275,000 as of 2023. [ 2 ]

Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation, perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural ...
For this reason, many experiments in psychology are conducted in laboratory conditions where they can be more strictly regulated. Alternatively, some experiments are less controlled. Quasi-experiment's are those that a researcher sets up in a controlled environment, but does not control the independent variable. For example, Michael R ...
Such traits, particularly body fat distribution, may represent sexual ornamentation, which is important in mating throughout the animal kingdom, for example, in birds. [113] [114] Humans also use bodily decoration, including jewelry, tattoos, scarification, and makeup to enhance appearance and desirability to potential mates. [107] [115]
The allocation is usually according to level of sperm competition, female novelty, and female reproductive quality. [17] An experiment performed on an external fertilizing fish called Rhodeus amarus , also known as the European bitterling, was used to show that sperm can be allocated differently if a novel partner is around, but that it also ...
