 In an interview with the Science Journal G. Wayne Clough , the 12th secretary of the Smithsonian Institution assuaged the animosities between critics and proponents of the exhibition : “ So I don 't think there 's anything negative here . I think the Smithsonian tried to do it right . When we heard the concerns , we asked the community to come together and talk about it , and we listened , and some people in that audience had their minds changed , as a matter of fact , but not everybody . So , I think it 's time in a situation like this to pause , and for the profession itself to say , " Okay , there 's a problem , what are you going to do about it ? And , you remember , the United States never signed the UNESCO treaty . ”
