How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.

The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage.

24. LECCIONES APRENDIDAS
1. La adaptabilidad de los 12 cultivares de Amaranthus fue
diferente, existiendo alta variabilidad en la mayoria de las
características evaluadas e influencia del ambiente en la
expresión de las mismas.
2. El mejor tratamiento en condiciones de costa central fue el
cv. Atacco (3.07 kg/m2, precoz).
3. Entre los cultivares asiáticos Mira y Amaranth Red Leaf fueron
los mejores tratamientos (1.60 y 1.52 kg/m2, calidad ).
4. Los cultivares Atacco (167.31 g/m2) y White Leaf (105.25 g/m2)
tuvieron el mayor rendimiento en seco.
5. En general, todos los cultivares demostraron su tendencia
hortícola, adicionalmente algunos ornamental.
6. Los factores limitantes más importantes fueron: la floración
prematura y aspectos de manejo agronómico (malezas, plagas
y enfermedades, manejo de densidad de siembra ).
7. Se ha demostrado un amplio potencial de distintas especies y
cultivares de Amaranthus.
25. INVESTIGACIÓN NECESARIA
1. Evaluar la adaptación de los cultivares de Amaranthus
del presente ensayo en diferentes climas específicos del
Perú a fin de determinar el verdadero potencial del
cultivo.
2. Realizar trabajos de mejoramiento genético y efecto de
distintas dosis de nitrógeno y abonamiento en el
rendimiento y calidad nutricional de diferentes cultivares
de Amaranthus como hortaliza de hoja.
- El poblador peruano se ve cada día más afectado por una serie
de enfermedades nutricionales, como consecuencia de una dieta
alimentaria deficiente, o bien a causa de un desbalance en la
misma.
