Damaging real lives through obstinacy: re-emphasising why significance testing is wrong
This paper reminds readers of the absurdity of statistical significance testing, despite its continued widespread use as a supposed method for analysing numeric data. There have been complaints about the poor quality of research employing significance tests for a hundred years, and repeated calls for researchers to stop using and reporting them. There have even been attempted bans. Many thousands of papers have now been written, in all areas of research, explaining why significance tests do not work. There are too many for all to be cited here. This paper summarises the logical problems as described in over 100 of these prior pieces. It then presents a series of demonstrations showing that significance tests do not work in practice. In fact, they are more likely to produce the wrong answer than a right one. The confused use of significance testing has practical and damaging consequences for people's lives. Ending the use of significance tests is a pressing ethical issue for research. Anyone knowing the problems, as described over one hundred years, who continues to teach, use or publish significance tests is acting unethically, and knowingly risking the damage that ensues

Physical attractiveness as a mediator of the impact of early pubertal changes for girls
The present study examined the effects of early pubertal development and physical attractiveness on the popularity, body image, and self-esteem of over 200 sixth-grade girls. Two rival hypotheses were explored. The first suggests that physically attractive girls, because of their more favorable social environment, will exhibit fewer psychosocial difficulties than unattractive girls during pubertal development. The second hypothesis argues that attractive girls will exhibit greater difficulty during pubertal transition because their self-image is more intimately connected with their physical appearance. Although there were no significant interactions between attractiveness and pubertal development for either popularity or body image, the second hypothesis was supported with respect to self-esteem. Specifically, developing attractive girls exhibited lower self-esteem than their unattractive counterparts. The results are discussed in terms of the relative vulnerability to bodily changes of girls differing in physical attractiveness.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45265/1/10964_2005_Article_BF02088640.pd
