Another difficult issue for the firstborn is that the younger child is always in his way. It is essential in a between-subjects experiment that the researcher assign participants to conditions so that the different groups are, on average, highly similar to each other. Carryover effects can be interesting in their own right. = 6 orders, ABCD = 4! In block randomization, all the conditions occur once in the sequence before any of them is repeated.
