Is stability a determinant of rock bands success?

Turns out, it seems not:

‘I make use of the characteristics of more than 6000 rock bands to empirically analyze if and how the stability of their members helps them to get a higher level of success. Bands cover all genres of Rock music (from Country to Punk), and their performance is assessed by having a song ranked in Billboard 100. Analyzing how the turn-over of members of a band affects their performance, it appears that the total number of musicians that left the band (compared to the actual number of musicians) – used as an indicator of instability –positively impacts the probability of a success. This may reveal that more talented musicians tend to be recruited after the departure of founding members, or that new members bring fresh ideas. The latter interpretation is supported by another result, showing that solo artists have a higher probability of success than bands. Finally, I also show that bands that come back to the stage after a split do not perform better.

donald trump is a national-security risk

‘Since 1952, the White House has allowed major-party candidates access to classified intelligence briefings so that they will be current on important issues if they win the election. trump should be denied this courtesy.

…The decision rests, as always, with the sitting president, and Joe Biden is likely to continue this practice so that he will not be accused of “politicizing” access to intelligence. Such accusations need not be taken seriously; they would only be more meaningless noise from a GOP that has already stumbled in a clumsy attempt to impeach Biden after leveling charges of corruption at both him and his son. And although denying trump access to classified briefs would produce squawks and yowls from Republicans, it would also serve as a reminder that trump cannot be trusted with classified information.

The risks of denying trump these early briefings are negligible. As we learned from his presidency, trump is fundamentally unbriefable: He doesn’t listen, and he doesn’t understand complicated national-security matters anyway. The problem with giving trump these briefings, however, isn’t that he’s ignorant. He’s also dangerous, as his record shows.

Indeed, if trump were ga federal employee, he’d have likely already been stripped of his clearances and escorted from the building…’ ( Tom Nichols via The Atlantic )
