Alasan Anak Sulung Lebih Cerdas Sebuah studi terkini yang dilakukan tim Universitas Edinburgh menemukan bahwa anak sulung memiliki kecenderungan lebih cerdas ketimbang anak kedua atau terakhir.
Hasil ini didapat setelah peneliti memeriksa data yang dihimpun Biro Statistik dan Tenaga Kerja Amerika Serikat, seperti dilaporkanZeenews yang dilansirSuara.com .
Peneliti menemukan bahwa tenaga kerja yang merupakan anak pertama dalam silsilah keluarganya memiliki tingkat IQ yang lebih tinggi dibandingkan tenaga kerja yang merupakan anak kedua, ketiga, dan seterusnya.
Pemimpin peneliti, Dr Ana Nuevo Chiquero menemukan bahwa saat memiliki anak pertama, orangtua cenderung mempersiapkan matang-matang dari segi nutrisi maupun pengasuhan.
Hal ini yang membuat anak pertama memiliki tingkat kecerdasan yang lebih baik ketimbang adik-adiknya.
Penelitian ini juga menunjukkan bahwa anak pertama biasanya lebih sukses dan ambisius karena dituntut dapat menjadi contoh bagi adik-adiknya.
Begitu pula dengan peluang melanjutkan ke tingkat pendidikan yang lebih tinggi, dimana anak sulung 16 persen lebih mungkin untuk melakukannya.
Studi sebelumnya juga menunjukkan bahwa sebagian besar orangtua memiliki anak yang paling disayang dan biasanya merujuk pada anak pertama.
