Recently, an online article suggested that an email sent by Elon Musk to his TESLA employees could be the sign of a premature end for the electrical car company (link A). This would apparently result from the decision of cutting the number of full time employees by roughly 7%. However, the article doesn’t clearly explain how such a cut could be related to the end the company. Perhaps most importantly, the original email mentioned in the article (link B) states also that TESLA grew by 30% during last year and that both the third and fourth quartiles saw a positive profit. Take home: the data are insubstantial and do not suggest any imminent collapse of the company.

Often media claim that digital technologies have a negative effect on the psychological wellbeing of young adults. However, a new analysis suggests that this claim could be unsupported. This analysis, performed on more than 350 thousands adolescents, shows that the association between the use of digital technologies and teen psychological wellbeing can explain just 0.4% of the variance in wellbeing. This effect is far too small to be of any practical use, and other major factor should be considered first. For example, the negative effects of smoking marijuana and bullying are x2.7 and x4 times larger the effect of digital technologies. Take home: spending time in front of computer has a minimal effect on the wellbeing of our children.
