MITT ROMNEY said in all three presidential debates that we need to expand the economy. But he left out a critical ingredient: investments in science and technology.

Scientific knowledge and new technologies are the building blocks for long-term economic growth — “the key to a 21st-century economy,” as President Obama said in the final debate.

So it is astonishing that Mr. Romney talks about economic growth while planning deep cuts in investment in science, technology and education. They are among the discretionary items for which spending could be cut 22 percent or more under the Republican budget plan, according to the Center on Budget and Policy Priorities.

According to the American Association for the Advancement of Science, the plan, which Mr. Romney has endorsed, could cut overall nondefense science, engineering, biomedical and technology research by a quarter over the next decade, and energy research by two-thirds.
