An Example of Picard's stupidity, in the episode "Timescape" Picard's mind was intoxicated by the effects of Temporal Narcosis, he felt compelled to draw a smiley face in a hovering cloud of gas near a warp core breach. He collapses in pain a few moments later, but first he giggles like a fool and points to his smiley face with pride, Kirk would never have done something this silly , see this clip,
