Think Twice

Better think before agreeing twice

Think twice before you tell

Answer to the Rhythm Puzzle At first glance the ECG looks very abnormal. The P-wave morphology is not compatible with sinus rhythm, the conduction intervals are normal, and the QRS complexes are very abnormal in amplitude (micro-voltages in the extremity leads). In lead II there is almost no signal at all. Althoughmicro-voltages in the extremity leads are a common feature in one of the most pre...

Vertebroplasty for osteoporotic fracture? Think twice.

Think twice before recommending vertebroplasty (VP) for symptomatic osteoporotic compression fractures. New studies suggest that it has little benefit; thus, VP should be considered only after other, more conservative options fail.

Think twice and then: combining or choosing in dialectical bootstrapping?

Individuals can partly recreate the "wisdom of crowds" within their own minds by combining nonredundant estimates they themselves have generated. Herzog and Hertwig (2009) showed that this accuracy gain could be boosted by urging people to actively think differently when generating a 2nd estimate ("dialectical bootstrapping"). Although the "crowd within" promises accuracy gains, it remains uncl...

Think twice: Impulsivity and decision making in obsessive–compulsive disorder

BACKGROUND AND AIMS Recent studies have challenged the anxiety-avoidance model of obsessive-compulsive disorder (OCD), linking OCD to impulsivity, risky-decision-making and reward-system dysfunction, which can also be found in addiction and might support the conceptualization of OCD as a behavioral addiction. Here, we conducted an exploratory investigation of the behavioral addiction model of O...
