WASHINGTON — The Trump administration has pursued policies that have hewed remarkably close to the recommendations of a leading conservative think tank, the Heritage Foundation, which found in a new review that nearly two-thirds of its ideas had been carried out or embraced by the White House over the past year.

Not one to dwell on the details of governing, President Trump has shown a considerable degree of deference to groups within the conservative movement like Heritage, leading to a rightward shift in social, environmental, immigration and foreign policy.

The results, Heritage found in its review, exceeded even the first year of Ronald Reagan’s presidency, whose tenure has long been the conservative gold standard.

“There is so much noise in this town that I think it obscures the real work that’s being done,” said Kay Coles James, the new president of the Heritage Foundation, which shook up its leadership last year after disagreements that stemmed in part from the perception that it was not acting effectively enough to shape the debate in Washington.
