<p>The issue of the impact of child-rearing on the careers of women in STEM fields is a really difficult one. If a woman chooses to remain childless, then she mainly has to deal with attitudinal and cultural barriers, but those can be overcome [to some extent, anyway] by a woman with great personal strength.</p>
<p>However, if we as a society set the expectation that a woman in a STEM career must choose to remain childless in order to be competitive, then I think we would be committing a great harm.</p>
<p>In my opinion, people who have not reared children think it is considerably easier than it is. This also tends to be true of women before they have children–we were all so easy to bring up, right?!</p>
<p>I have one child, QMP. For most of QMP’s school years, we hired an in-home nanny for 50 hours a week. Suppose that QMP averaged 9 hours of sleep a night. How many hours per week did that leave me in charge? Try guessing before you do the math, unless you already knew before you got to this sentence. Actually, this is a trick question, because one or two of the hours that QMP was sleeping were times when the nanny was there, not I. So, actually the time amounted to 60-65 hours per week of responsibility for a child. An exceedingly small fraction of those hours could be spent on work. You might also think it was a trick question, because I asked about leaving <em>me</em> in charge. But I know very few families where the responsibility for child-rearing is divided anywhere near to equally between the adult partners. The responsibility also curtailed my academic travel substantially, relative to several of the men in my (approximate) career cohort. It was truly impossible for me to travel as much as they did. There are career costs connected with this. Then, put this in a context where my faculty colleagues imagine that delaying the tenure clock for a woman by one year is a fair trade-off for the time demands of child-rearing.</p>
<p>Of course many women in STEM want to have children! Some of them want children very badly! It’s not something that it would be beneficial for society to foreclose, as a possibility. But I had a long period when I had to shift from doing “my best work” to doing “the best work that is possible under the circumstances.” </p>
<p>I would not choose differently–absolutely not!–now that I understand the circumstances better. Having a family has many very deep rewards. But it is decidedly a challenge.</p>
<p>One remark not connected specifically with the remarks above, but with one of JHS’s comments: I chaired our department for a number of years. The Dean (male) remarked to me once that the chair of another department (also male) met with him one-on-one for lunch once a week. He thought it would be better if we did that, too. Um, no–that arrangement is really not workable in our area. (It would probably be ok elsewhere.) Too bad, but no. </p>
