DISCUSSION: This question tests your understanding of the scientific method, a common LSAT theme.
In a proper experiment, you should keep all the variables the same, except for the variable you’re testing.
So the dummies should be the same, except for the breast stripe.
___________
- This would strengthen the experiment, by showing that the behavior is common to all titmice, and not just those from a particular flock.
- CORRECT. If this is true, then the titmice might have been reacting to some other difference, and not the change in stripe size.
- The size of the breast stripe didn’t correlate with age (lines 43-45), so the age of the birds shouldn’t matter.
- As long as the food was something that the titmice wanted to eat (and was always the same), then this wouldn’t matter. The birds could likely see the breast stripe before they saw what food was in the tray.
- This somewhat supports the hypothesis. The idea was that symbols such as stripes would determine status and avoid the need for fights.
Or perhaps once an aggressive bird got close enough, it would realize the experimental bird was a dummy.
